LiteSpeed vs Apache: Which Webserver is better for WordPress?

A Dedicated Server, also known as a Bare Metal Server, is a physical server where all resources (CPU, RAM, storage, bandwidth) are exclusively reserved for a single client, without sharing with anyone else. The client has full control to manage this server, including both hardware and software.

Key Characteristics of a Dedicated Server:

• Exclusive Resources (No Sharing): You get to use 100% of the physical server's resources—from CPU and RAM to storage—without having to share performance with any other clients.
• Full Control: You have the highest level of access—(Root Access) for Linux servers or (Administrator) for Windows Server—allowing full authority to install operating systems, configure software, and optimize the system as you wish.
• High and Stable Performance: By not sharing resources, a dedicated server delivers the highest "bare metal" performance and superior stability for demanding applications.
• Enhanced Security: The physically and resource-independent environment minimizes security risks compared to resource-sharing solutions on the same server, such as a VPS.
• Superior Customization: A dedicated server can be flexibly configured to meet specific technical requirements, from web servers, databases, and game servers to virtualization systems.
• Investment Cost: The rental cost is typically higher than a VPS, as you are leasing an entire physical server instead of just a portion of its resources.

When should you choose a Dedicated Server?

• Websites with extremely high traffic or large-scale e-commerce systems.
• Enterprise applications and databases that demand high processing performance.
• Projects that require specific software or OS configurations not supported in a shared environment.

Why lease a Dedicated Server in Vietnam from VietHosting?

Choosing between a Large VPS and a Dedicated Server is a decision between a top-tier virtualized environment with high flexibility and an exclusive physical environment for maximum performance. Here are the core differences to help you make the right choice.

Detailed Comparison: Large VPS vs. Dedicated Server

1. Nature and Resources:

• Large VPS: A powerful virtual server created from a parent physical server. CPU and RAM resources are still 100% dedicated thanks to KVM virtualization technology.
• Dedicated Server: An entire physical server. You have exclusive use of 100% of its hardware without any virtualization layer.

2. Performance:

• Large VPS: Offers very high and stable performance, nearly equivalent to a physical server, but theoretically has a small overhead from the virtualization layer.
• Dedicated Server: Delivers absolute "bare metal" performance, making it the most powerful choice for the most demanding tasks.

3. Management and Flexibility:

• Large VPS: Can be provisioned, upgraded, or downgraded automatically and quickly within minutes.
• Dedicated Server: Requires time for technicians to physically install hardware and perform manual setup (typically 4-8 hours). Hardware upgrades are more complex.

4. Cost:

• Large VPS: More cost-effective as it shares common infrastructure costs like rack space, networking, and power.
• Dedicated Server: Higher rental cost as you are paying for an entire piece of exclusive hardware.

Summary: When to Choose Which Solution?

• Choose a Large VPS when: You need massive resources and high performance close to a dedicated server, but still prioritize flexibility in upgrades and cost optimization.

• Choose a Dedicated Server when: Your application demands absolute hardware performance, requires deep hardware customization, or has specific security needs that mandate a completely physically isolated environment.

LiteSpeed Web Server (LSWS) and Apache are two of the most popular web servers, but they are built on different architectures, leading to significant differences in performance, cost, and features. The choice between them depends on your top priorities.

Detailed Comparison: LiteSpeed vs. Apache

1. Architecture and Performance:

• LiteSpeed: Uses an event-driven architecture, which handles thousands of concurrent connections with very few resources (CPU, RAM). This architecture allows LSWS to process PHP and static content many times faster than Apache.
• Apache: Uses a process-based architecture, creating a new process for each connection. This architecture is simple and reliable but consumes more resources under high traffic.

2. Caching:

• LiteSpeed: Comes with a powerful, built-in, server-level caching solution, LSCache, which is one of the most effective website acceleration tools available today (especially for WordPress).
• Apache: Does not have a similar built-in caching system. To accelerate performance, users need to install and configure third-party cache modules or plugins.

3. Compatibility and Configuration:

• LiteSpeed: Is designed as a drop-in replacement for Apache and is fully compatible with .htaccess rules without modification.
• Apache: Is the gold standard for .htaccess compatibility, supported by most applications and tutorials.

4. Cost and Licensing:

• LiteSpeed: Is a commercial software, requiring a paid license to use its full-featured premium versions.
• Apache: Is completely free and open-source.

Summary: When to Choose Which Solution?

• Choose Apache when: You need a free, stable solution with a huge support community and do not require top-tier performance.

• Choose LiteSpeed when: Your top priority is page load speed, high traffic capacity, and built-in acceleration features, especially for high-traffic WordPress websites.

Both cPanel and DirectAdmin are leading control panels, but recent changes in pricing policies have made the comparison more critical than ever. The choice is no longer based on habit, but on your actual priorities regarding performance, cost, and ecosystem.

Detailed Comparison: cPanel vs. DirectAdmin

• Performance & Resources:

  • DirectAdmin is the clear winner here. With its lightweight architecture, it consumes less RAM/CPU, helping the server run faster and leaving more resources for your websites.

  • cPanel, being more feature-rich, consumes slightly more resources.

• Pricing & Licensing Policy:

  • DirectAdmin has a significantly lower license cost and typically does not limit user accounts, making it easy to control costs as you grow.

  • cPanel uses a per-account pricing model, which can become expensive if you need to host a large number of websites.

• UI & User Experience:

  • cPanel still holds the edge in being extremely beginner-friendly with its familiar and intuitive interface.

  • DirectAdmin, with its new Evolution skin, is very modern, clean, and highly customizable, favored by experienced users and developers.

• Ecosystem & Extensibility:

  • cPanel boasts a massive ecosystem of third-party plugins and apps (Softaculous, JetBackup...), offering nearly limitless extensibility.

  • DirectAdmin also has popular plugins, but its ecosystem is smaller compared to cPanel's.

Ultimately, the choice between cPanel and DirectAdmin is a trade-off between a convenient, familiar ecosystem and a solution optimized for performance and cost. Whatever your decision, VietHosting provides genuine cPanel licenses and DirectAdmin licenses at the best prices to support your needs.

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.

A Server License is a legal permit to install and use specialized software on a server (including a VPS or a Dedicated Server - this license can be for an operating system, management software, or security application...). This not only ensures the legal right to use the software but is also a key factor in ensuring it performs optimally, receives security updates, and gets direct technical support from the developer.

Why are Server Licenses necessary?

Using licensed software is not just about legal compliance; it also provides critical technical benefits that help your system run stably and securely:

• Technical Support: You gain access to direct support from the developer when you encounter issues.
• Updates and Security: You consistently receive the latest updates, including crucial bug fixes and security patches.
• Full-Featured Access: You unlock all the premium features of the software that are unavailable in free or non-licensed versions.
• Stability: It ensures that the software operates at the performance level committed by the developer.

Common Types of Server Licenses

Server licenses typically apply to foundational software that plays a core role in service operations:

• Enhanced Operating Systems: e.g., CloudLinux OS to improve hosting stability and security.
• Control Panels: e.g., cPanel and DirectAdmin for hosting management.
• High-Performance Web Servers: e.g., LiteSpeed Web Server to accelerate websites.
• Security Software: e.g., Imunify360 for automated protection against malware and attacks.

Why purchase a Server License from VietHosting?

As an official partner in Vietnam for major international software vendors like cPanel, DirectAdmin, CloudLinux, and LiteSpeed, VietHosting offers a full range of popular server licenses at competitive prices with a fast activation process.

When you get a license from us, you not only ensure legal compliance but also receive free initial installation support from our technical team, helping you get your system up and running efficiently and securely.

Colocation (also known as Server Colocation) is a service that allows a business or individual to rent space (by the U or as a full Rack) in a professional data center facility to place their own Servers or network equipment.

Instead of investing in and operating a costly private server room, you get to leverage the Data Center's superior infrastructure, including power, cooling, high-speed internet connectivity, and physical security. In this model, the client retains full ownership and management of their equipment, while the service provider ensures the infrastructure operates with constant stability and security.

By using a colocation service, you benefit from:

• Professional Infrastructure: Your server operates in an environment with standard-compliant backup power, standard cooling systems, and automated fire suppression.
