Frequently Asked Questions (FAQ)
Frequently Asked Questions and Essential Knowledge about VietHosting Services
Can I install Windows on KVM VPS?
Yes. You can install Windows Server on KVM VPS services at VietHosting.
With KVM (Kernel-based Virtual Machine) virtualization, each VPS operates similarly to an independent physical server with dedicated CPU, RAM, and storage resources. This allows the VPS to run multiple operating systems, including Windows Server, reliably.
Commonly supported Windows Server versions include:
Note: Windows Server requires a valid license. Customers may provide their own license (BYOL – Bring Your Own License) or purchase a license through VietHosting.
What factors affect VPS CPU performance?
The CPU performance of a VPS (Virtual Private Server) depends on several factors, including the physical server processor, the virtualization technology used, and the number of CPU cores allocated to each VPS instance.
Modern VPS environments typically use virtualization technologies such as KVM, allowing CPU resources to be allocated directly from the physical server while maintaining isolation between virtual machines.
CPU performance may also be influenced by overall server workload and how efficiently resources are managed by the hosting provider.
What is Disk I/O and why is it important for VPS performance?
Disk I/O measures how quickly data can be read from or written to the storage system of a VPS. It is one of the key factors that affect website and application performance.
Whenever a website loads files or retrieves data from a database, the server performs read and write operations on the storage system. If Disk I/O performance is limited, the website may respond slowly or experience delays.
Modern VPS infrastructures typically use SSD or NVMe storage, often combined with RAID configurations, to deliver faster data access and improved reliability.
How to test VPS performance with VH Benchmark?
To test VPS performance, you can run the VH Benchmark Script directly on a Linux server using a single Bash command.
curl -Lso- https://mirrors.viethosting.com/scripts/vh-benchmark.sh | bashOnce executed, the script automatically collects system information and performs performance tests for CPU, Disk I/O, and network speed across multiple domestic and international nodes.
