Q: Does VietHosting guarantee Network Speed?

VietHosting operates on a shared bandwidth model for its services. Therefore, the advertised network speeds (e.g., Domestic Bandwidth 1 Gbps, International Bandwidth 32 Mbps) represent the maximum allowed speed that VietHosting's system sets and limits for your service on our shared network infrastructure. This is not the same as dedicated bandwidth reserved solely for each customer. Because this bandwidth resource is shared among multiple users and the maximum speed is limited by the system, VietHosting does not guarantee that you will consistently achieve this maximum allowed speed. Actual speeds will depend on the overall network traffic at the time of use and our bandwidth management policies. In order to maintain overall network stability, fairness, and service quality, VietHosting reserves the right to apply traffic shaping or rate limiting measures if sustained bandwidth usage exceeding the allowed thresholds is detected and is deemed to adversely affect the infrastructure or other customers. In such cases, bandwidth may be temporarily restricted to a minimum level of 10 Mbps. Any applied limitation will be removed and bandwidth restored to its original configuration once usage returns to acceptable levels, no longer impacts the shared system, or after the customer has implemented appropriate corrective measures as advised by VietHosting. Private (Dedicated) or policy-based bandwidth is provisioned with independent policy groups applied exclusively to the associated service, enabling greater control and more consistent performance compared to shared bandwidth. If you require stable network speeds or guaranteed dedicated bandwidth for your service, please contact VietHosting directly. We will provide detailed consultation and pricing for suitable dedicated bandwidth solutions.

2. Why Benchmark Your VPS or Server?

Benchmarking a VPS or server allows you to assess the system's actual performance, helping you identify potential bottlenecks related to CPU, storage speed (Disk I/O), or network bandwidth limitations.

By reviewing the result tables, you can easily verify whether the hardware configuration matches the provider's commitments. It also provides objective data for comparing different hosting providers before deploying your system into a production environment.

3. Key Benchmarking Metrics

Upon execution, the script gathers and benchmarks the most critical components that determine server performance:

System Information: Displays CPU model, core count, clock frequency, RAM capacity, disk space, operating system, and virtualization technology (e.g., KVM, VMware).
Disk I/O Performance: Tests sequential write speed using the dd command and automatically measures random 4K read/write speeds using fio if installed.
Network Speed: Measures download speeds from network nodes in Vietnam and multiple international regions (Asia, Europe, Americas).
ISP Information: Displays the server's public IP address, ASN, and network provider name.

4. How to Install and Use VH Benchmark Script

The benchmarking process is typically completed very quickly, taking only 2–3 minutes depending on your VPS configuration and network connection speed.

4.1. Install Required Packages

System Requirements

The server must have curl installed to download the script. It is highly recommended to install fio so the script can measure disk IOPS accurately.

If your server does not have these libraries installed, run the command corresponding to your operating system (Login via SSH as root):

For Ubuntu / Debian:

BASH / TERMINAL

apt-get update -y && apt-get install curl fio -y

For CentOS / AlmaLinux / Rocky Linux:

BASH / TERMINAL

dnf install curl fio -y

* For older distributions such as CentOS 7, you may need to install epel-release and use yum instead:

BASH / TERMINAL

yum install epel-release -y && yum install curl fio -y

Frequently Asked Questions and Essential Knowledge about VietHosting Services

What is VH Benchmark Script?

VH Benchmark Script is an open-source Linux benchmarking tool designed to test CPU performance, disk I/O speed, and network bandwidth of a VPS or dedicated server. VH Benchmark Script provides a quick and comprehensive overview of your system's capabilities directly in the terminal within minutes.

How to benchmark a Linux VPS with VH Benchmark Script?

Benchmarking a Linux VPS refers to measuring CPU performance, disk I/O speed, and network bandwidth to evaluate the real performance of a virtual server (VPS). You can perform this benchmark quickly using the VH Benchmark Script by executing a single Bash command:

curl -Lso- https://mirrors.viethosting.com/scripts/vh-benchmark.sh | bash

Expert Insight: VH Benchmark Script includes dedicated test nodes for major Vietnamese ISPs such as VNPT, Viettel, and FPT, providing realistic network speed results for users located in Vietnam.

What results should you expect from a VPS benchmark test?

A typical VPS benchmark result shows CPU information, disk I/O performance (MB/s and IOPS), and network download speeds across multiple regions. Upon completion, the VH Benchmark Script outputs an intuitive table displaying these metrics and automatically saves a detailed log file in your root directory.

These transparent benchmark results empower you to accurately verify hardware commitments, ensuring your Dedicated Server or VPS meets all production requirements before deployment.

Which Linux systems support the VH Benchmark Script?

The VH Benchmark Script supports most major Linux distributions out of the box, including Ubuntu, Debian, CentOS, AlmaLinux, and Rocky Linux. It requires no complex dependencies—only the curl package to download the script and the fio library for accurate disk I/O measurement.

VietHosting designed this tool for maximum compatibility, ensuring seamless benchmarking across most popular Linux distributions.

How does VH Benchmark Script avoid API rate limits?

VH Benchmark Script avoids API rate limits by integrating an automatic fallback mechanism that switches to alternative network nodes if a limit is detected. This prevents the script from failing or stalling, which is a common issue with standard benchmarking tools during frequent automated network testing.

Reliability: This robust mechanism ensures uninterrupted and accurate speed tests, allowing system administrators to reliably evaluate network stability without tool-induced bottlenecks.

How to test VPS network speed by region with VH Benchmark Script?

Testing VPS network speed by region helps measure bandwidth and routing performance to domestic or international servers. You can limit the testing scope by appending specific parameters: use curl -Lso- https://mirrors.viethosting.com/scripts/vh-benchmark.sh | bash -s vn for Vietnam nodes exclusively, or -s intl for international download speeds.

These parameters are ideal for verifying shared bandwidth configurations, such as the 1 Gbps domestic and 32 Mbps international routing offered by VietHosting VPS plans in Vietnam.

Why does VH Benchmark Script use FIO for disk I/O testing?

Standard tools such as dd only measure sequential write speeds, which is not sufficient for accurately benchmarking disk I/O performance on a VPS. Modern applications such as databases, web servers, and caching systems rely heavily on random disk access. Therefore, VH Benchmark Script uses the fio utility to measure:

Total IOPS (Input/Output Operations Per Second)
Disk access latency
Random 4K Read/Write speeds

When deploying a powerful KVM VPS or a high-resource Large VPS at VietHosting, the underlying SSD RAID-10 storage can deliver high IOPS performance under real workloads, which can be verified directly using the FIO utility.

An Explanation of Bandwidth (Mbps, Domestic, International)?

1. What is Bandwidth?

Bandwidth is the maximum data transfer capacity of a network connection over a specific period, typically measured in Mbps (Megabits per second) or Gbps (Gigabits per second).

To make it easier to understand, you can think of bandwidth like the width of a highway. The wider the road, the more cars can travel at the same time. Similarly, the larger the bandwidth, the more data (images, videos, text) can be transferred between your website and your users per second.

2. Understanding Megabits (Mbps) vs. Megabytes (MB/s)

This is the most common point of confusion. Network service providers (including VietHosting) typically advertise bandwidth speed in Megabits per second (Mbps), but the file download speed in your browser is shown in Megabytes per second (MB/s).

The conversion rule is simple: 1 Megabyte = 8 Megabits.

To calculate the theoretical maximum download speed (in MB/s), you simply divide the advertised speed (in Mbps) by 8.
Example: A hosting plan with 100 Mbps bandwidth will have a theoretical maximum download speed of 100 / 8 = 12.5 MB/s. The actual speed might be slightly lower due to transmission overhead, which is why you might see speeds around 10-12 MB/s.

3. Domestic Bandwidth

This is the data transfer rate for network connections within Vietnam's territory. This bandwidth is optimized for high speed and extremely low latency, making it ideal for websites and applications primarily serving users in Vietnam.

4. International Bandwidth

This is the data transfer rate for connections from Vietnam to other countries and vice versa. Due to long geographical distances, international bandwidth typically has higher latency and lower committed speeds compared to domestic bandwidth.

5. Shared Bandwidth Policy at VietHosting

To provide services at a reasonable cost, we operate on a shared bandwidth model. This means the advertised network speed is the maximum port speed your service is connected to. If your project requires guaranteed network speeds or needs dedicated bandwidth, please contact us for a consultation on a suitable solution.

What is a Vietnam VPS?

A Vietnam VPS is a virtual server created from a physical server located in a Data Center in Vietnam and has a Vietnamese IP address. It is the top choice for websites and applications targeting users within the country, thanks to superior access speeds and extremely low latency.

Additionally, you might encounter variants like Viettel VPS, VNPT VPS, or FPT VPS. These are VPS services created from physical servers in the respective carriers' data centers, designed to serve needs for an IP from a specific carrier. Essentially, they are a form of Vietnam VPS.

Technical Working Principle

A Vietnam VPS operates on virtualization technology, which divides a powerful physical server into multiple independent virtual environments:

Resource Virtualization: A physical server (located in Vietnam) has a virtualization software layer (a hypervisor) like KVM installed. This layer partitions the hardware resources (CPU, RAM, storage) into separate portions.
Dedicated Allocation: Each portion of resources is allocated to a single VPS, meaning your VPS has its own amount of RAM and CPU and is not affected by other users, providing superior stability.
Independent Operation: Each VPS functions like a true dedicated server, allowing you to install your own operating system (Linux, Windows) and have full administrative control (root / Administrator).
Inherited Geographic Advantage: Since the underlying physical server is in Vietnam, your VPS automatically benefits from extremely fast access speeds and is optimized for Local SEO within the domestic market.

Key Benefits of a Vietnam VPS

Choosing a Vietnam VPS offers numerous competitive advantages for projects focused on the domestic market:

Superior Access Speed: Minimizes network latency for users in Vietnam, enhancing user experience and customer retention.
Full Administrative Control: Allows for the installation of custom software and deep configuration to meet any project's specific requirements.
Dedicated Resources: Ensures stable performance that is not affected by other users on the same physical server.
Local SEO Advantage: A Vietnamese IP address is a crucial signal that helps websites rank higher in search engines for the Vietnamese market.
Stable Connectivity: Less affected by international submarine cable incidents, ensuring service continuity.
Convenient Support: Services in Vietnam offer the advantage of support in Vietnamese, making it easy for customers to discuss needs, resolve issues, and receive advice without language barriers or time zone differences.

What is an Offshore VPS?

An Offshore VPS (often referred to as an "International VPS" or "Overseas VPS") is a virtual server created from a physical server located in a data center in a country different from that of the user or their company. This is often done to reach a local market in that country or to take advantage of different legal or cost policies.

For users in Vietnam, an Offshore VPS is any service with a physical server located outside of Vietnam. Common options are often named by location, such as VPS USA, VPS Singapore, or VPS Hong Kong. An offshore VPS is suitable when you need to reach an international audience, but it will have higher latency when accessed from Vietnam.

Technical Working Principle

When a user from Vietnam accesses an Offshore VPS, the data stream must travel a long distance, which leads to the following technical characteristics:

International Routing: Data must travel through multiple international gateways and submarine fiber optic cable systems to reach the server abroad.
High Latency: The long physical distance significantly increases network latency, making the VPS's response time slower compared to a domestic VPS.
Reliance on International Infrastructure: Connection speed and stability are entirely dependent on international network infrastructure. Incidents like submarine cable breaks will cause severe performance degradation.

Key Benefits of an Offshore VPS

An Offshore VPS is a suitable solution that offers many benefits for internationally-oriented projects:

Reach International Markets: Optimizes speed and experience for users near the data center's region (e.g., a Singapore VPS is optimal for Southeast Asian users).
Flexibility in Legal and Policy Matters: Allows services to be hosted in countries with specific legal regulations on data, copyright, etc., that fit the project's needs.
Geographic Location Diversity: Provides a wide choice of countries for server location, helping to optimize for each specific target market.

Key Drawbacks When Used in Vietnam

While useful for international markets, an Offshore VPS presents significant barriers when you need to serve users in Vietnam:

Slow Speed: Access speed from Vietnam is considerably slower and less stable due to reliance on international submarine cable infrastructure.
Support Barriers: You may face difficulties when urgent technical support is needed due to language barriers (usually English) and time zone differences.
IP & Local SEO Disadvantages: A foreign IP address is not prioritized for searches in Vietnam, and the quality ("cleanliness") of the IP range needs to be carefully verified.
Complex Payment & Legal Issues: Often requires international credit cards, carrying currency exchange risks, as well as potential legal issues regarding user data storage.

Applications and Use Cases

An Offshore VPS is an essential choice for the following scenarios:

Global Applications/Services: Web applications or SaaS platforms with users in many different countries.
International Game Servers: Serving players from a specific region or around the world.
VPN/Proxy Services: Creating network access points in desired countries.
Projects with Specific Jurisdictional Requirements: Storing data or hosting services in countries with a suitable legal framework.

How to Choose a High-Quality Vietnam VPS?

Choosing a high-quality Vietnam VPS is a strategic investment decision that goes beyond simply finding a low-priced plan. A truly reliable service must ensure long-term stable performance, which depends on several technical factors that not all providers disclose. Here are the crucial criteria you should use for your evaluation:

Virtualization Platform:
This technology determines the level of resource independence. KVM (Kernel-based Virtual Machine) is considered the gold standard as it provides completely separate and dedicated resources (CPU, RAM), superior to older platforms like OpenVZ or XEN.
Physical Server (Node) Hardware Configuration:
The performance of your VPS is directly dependent on the parent server. Evaluate the CPU (prioritize enterprise-grade server CPUs like Intel Xeon Gold / Platinum) and the storage type (it should be Enterprise SSD or NVMe in a RAID-10 configuration for speed and data safety).
"Overselling" Policy:
This is a critical but often overlooked factor. Ask the provider about the maximum number of VPS instances per physical server. If a node is shared among too many virtual machines, network speed and disk I/O will be severely degraded, even with KVM virtualization.
Bandwidth & Network Connection:
You must evaluate both types of bandwidth. Domestic bandwidth determines the connection speed for users within Vietnam, while international bandwidth affects global users. A reputable provider should offer a clear commitment to a minimum guaranteed bandwidth, not just a maximum "up to" figure.
Scalability and IP Address Quality:
A good service must allow for easy upgrades and the addition of IP addresses. For tasks like SEO or Email Marketing, being allocated clean IPv4 addresses (not on any blacklists) is extremely important.
Technical Support:
A 24/7 support commitment should be verified by the speed and quality of responses from a professional technical team, not just an automated ticketing system.
