4. vpsbench - In-depth Testing with UnixBench

This is a powerful tool focused on running the full UnixBench suite, an industry standard for measuring the overall performance of a Unix-like system. It also includes disk and network speed tests. The UnixBench score is particularly useful for comparing CPU performance across different servers.

How to run:

wget https://raw.githubusercontent.com/mgutz/vpsbench/master/vpsbench && bash vpsbench

5. vHWINFO - View Virtual Hardware Information

Unlike the others, vHWINFO is not a benchmarking tool but a script designed to display detailed hardware information. It's very useful for checking if your provider has allocated the correct CPU type, virtualization technology (KVM, OpenVZ), disk info, and RAM.

How to run:

wget --no-check-certificate https://github.com/rafa3d/vHWINFO/raw/master/vhwinfo && chmod +x vhwinfo && ./vhwinfo

6. speedtest-cli - The International Network Speed Specialist

If you want to check your network speed to international servers, speedtest-cli is the best tool for the job. It's the command-line version of the well-known Speedtest.net service, providing accurate information on Download speed, Upload speed, and latency (ping).

How to install and run:

# For Ubuntu/Debian
sudo apt-get install speedtest-cli

# For CentOS/RHEL
sudo yum install speedtest-cli

# Run the test
speedtest-cli

Conclusion

Hopefully, with these six tools, you can confidently check and better understand the quality of the server you are using. Understanding your system's performance is a critical step in optimizing applications and ensuring the best user experience.

KVM VPS is a Virtual Private Server (VPS) that uses KVM (Kernel-based Virtual Machine) virtualization technology. This is true hardware-level virtualization, integrated directly into the Linux kernel, allowing each VPS to operate as a completely independent physical server.

Key Advantages of KVM VPS:

  • 100% Dedicated Resources: Each KVM VPS is allocated a private amount of RAM, CPU, and disk space, which is not shared and is not affected by the performance of other VPSs on the same server.
  • Full Kernel Customization: Since each VPS has its own kernel, users have full control to customize and install kernel modules, providing maximum flexibility.
  • Broad OS Compatibility: KVM supports the installation of Linux, Windows, and other custom operating systems via an ISO file.
  • Higher Security: The complete isolation between VPSs enhances security, effectively preventing local attacks.

High-Performance KVM VPS at VietHosting:

VietHosting's KVM VPS service is built on a powerful hardware platform featuring Intel Xeon Platinum CPUs and Enterprise SSD RAID-10 storage, combined with the advantages of KVM technology to deliver a stable, secure, and powerful virtual server solution for any project.

Large VPS is a line of Virtual Private Server (VPS) products designed with exceptionally large resource configurations (CPU, RAM, disk space), comparable to a mid-range physical server. It is the ideal solution for websites and applications with high traffic or heavy processing demands that require power close to a dedicated server but at a more optimized cost.

When should you choose a Large VPS?

  • When standard KVM VPS packages no longer meet your resource needs.
  • When you require high performance for large systems like E-commerce, ERP, CRM, or game applications.
  • When you want the power of a dedicated server but with the more affordable price and flexible management of a VPS.

  • Enterprise applications and databases that demand high processing performance.
  • Projects that require specific software or OS configurations not supported in a shared environment.

Colocation Service allows businesses and individuals to place their own servers in a professional data center facility. Instead of building and operating a costly server room, you rent space in a provider's data center.

By using a colocation service, you benefit from:

  • Professional Infrastructure: Your server operates in an environment with international standards for power, cooling, and fire suppression.
  • High-Speed Network Connectivity: Enjoy high-bandwidth, stable, and redundant internet connections.
  • Strict Physical Security: The data center is protected 24/7 with multiple security layers, surveillance cameras, and access control.
  • Cost Savings: Reduce infrastructure investment and operational costs compared to building your own facility.

In simple terms, you bring your server to our "home," and we ensure that "home" is always secure, cool, and has the best network connection. VietHosting offers initial setup support and associated server management services if needed.

Server Licenses grant the legal right to use specific software essential for managing, optimizing, or securing a server environment.

Unlike typical desktop software licenses, these are often required for operating systems (like CloudLinux), control panels (such as cPanel or DirectAdmin), web servers (like LiteSpeed), virtualization software, or security applications running on your VPS or Dedicated Server. Purchasing or renting these licenses ensures you receive updates, support, and operate legally within the software provider's terms.

SSL (Secure Sockets Layer) is a global security technology standard that encrypts the connection between a web server and a user's browser. An SSL Certificate is a data file installed on a server that acts as a digital "passport" to authenticate the website's identity and enable the HTTPS protocol (HTTP over SSL).

When a website has SSL (HTTPS), it ensures:

  • Data Encryption: All information exchanged between the user and the website (such as passwords, credit card details, personal data) is encrypted, preventing malicious actors from eavesdropping.
  • Data Integrity: Data cannot be altered or forged during transmission.
  • Authentication: SSL confirms that the user is connecting to the correct server for the website they intend to visit, not a fraudulent one.

Today, SSL is a mandatory requirement for all websites, not only for security but also as a crucial factor for Google SEO ranking and building customer trust.
