How can we test the performance of Vps hosts? Although VPS is a virtual independent server, it also determines the performance by cpu and memory, therefore, the performance of a vps host determines the speed at which website programs exist on the host. Some host providers provide you with test hosts. Of course, even if you do not have a test, you can buy it by yourself. Generally, you will be offered a full refund period of one month. You can use the performance testing software of the vps host to check the performance.

UnixBench is a good Linux-based VPS performance testing software. Unix00004.10:
Run the following command to start over SSH: ~ # Wget
[Root @ ~] # Tar xzf unixbench-4.1.0-wht.tar.gz
[Root @ ~] # Ls
Unixbench-4.1.0-wht-2 unixbench-4.1.0-wht.tar.gz
[Root @ ~] # Cd unixbench-4.1.0-wht-2/
[Root @ unixbench-4.1.0-wht-2] # make
[Root @ unixbench-4.1.0-wht-2] #./Run
We can obtain the vps host performance value of linux according to the method shown above. A larger value indicates better performance.
For example, the following host performance table:

Final score 475.4
Its performance value is 475.4, indicating that its capability is very good. Generally, the vps value of 256 of memory is about 200. Of course, this value is for reference. You need to take time to test stability and compatibility.
