How to check your VPS Performance

[Jovani]

I bought a VPS some months ago. Although my web hosting showed me featured and statistics about your VPS but I have still wanted to know exact things about my VPS getting. But how to check VPS performance, after some researches, I have some easy ways to check my VPS performance

Check the number of the number of cores, processor, CPU speed..etc on your VPS

Although these parameters showed out their websites and you can see them before you buy, but it's best to manually check whether these parameters coincide with things you are paying for.

To view the number of processors, you can use the command to check with nproc, after entering the command, the server will return the results as the number of processors are available.

Command:

nproc

*
That means you have 4 processors on a server.

To test more parameters such as CPU speed, number of cores, cache,..etc. Using the following command:

less /proc/cpuinfo

For example, the result returned:

processor: 0
vendor_id: GenuineIntel
cpu family: 6
model: 60
model name: Intel (R) Xeon (R) CPU 3.40GHz @ v3 E3-1231
stepping: 3
cpu MHz: 3400.321
cache size: 8192 KB
physical id: 0
siblings: 8
core id: 0
cpu cores: 4

initial apicid: 0
FPU: yes
fpu_exception: yes
cpuid level: 13

Press Ctrl + Z to exit.

It is the manipulation of test performance server that I use most often because of the thorough inspection will help you not to waste your money because sometimes, we spent money to buy one VPS or Dedicated is not cheap. Hopefully it will be more useful to you.

Good tips
I want to add additional information by checking speed of your network for a VPS
Because network speed is a very important factor since it directly affects the speed of your website. Even if you have a powerful server anywhere but possesses a poor line speed is slower then usual.

Therefore, you should test by entering the following command:

wget put_a_download_link_file_here -O - -o /dev/null | bash

Press Ctrl + Z to stop testing

The result returned is the speed of downloading files from many different servers around the world.

Instal SpeedTest.net. It is a well known Internet speed test available by simply accessing their site on any web browser that supports Flash. But they do also provide another way to conduct the test, via command line. So here it is the tutorial is all about.

I think nproc and less /proc/cpuinfo are commands to check server specs than showing you performance of your server.
If you want to know your server performance, you can run this command

(curl -s wget.racing/nench.sh | bash; curl -s wget.racing/nench.sh | bash) 2>&1 | tee nench.log

for example, I got the result when running it on my VPS

[root@vps1787 ~]# (curl -s wget.racing/nench.sh | bash; curl -s wget.racing/nench.sh | bash) 2>&1 | tee nench.log

You can find a lot information from dashboard. If CPU or RAM reach too high, you should upgrade your VPS.
