How to check your VPS Performance
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.
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:
cpu family: 6
model name: Intel (R) Xeon (R) CPU 3.40GHz @ v3 E3-1231
cpu MHz: 3400.321
cache size: 8192 KB
physical id: 0
core id: 0
cpu cores: 4
initial apicid: 0
cpuid level: 13
flags: FPU VME de PSE TSC MSR pae mce apic sep mtrr pge mca CX8 cmov dts acpi mmx pat pse36 clflush fxsr SSE SSE2 ss ht tm syscall nx PBE pdpe1gb rdtscp lm constant_tsc arch_perfmon PEBS BTS rep_good xtopology nonstop_tsc aperfmperf PNI pclmulqdq dtes64 ds_cpl VMX monitor SMX est tm2 cx16 SSSE3 FMA xtpr pdcm pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave AVX f16c rdrand lahf_lm abm Arat epb xsaveopt PLN pts dts tpr_shadow vnmi flexpriority EPT VPID fsgsbase Bmi1 hle AVX2 smep bmi2 Erms invpcid RTM
clflush size: 64
address sizes: 39 bits physical, 48 bits virtual
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.

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

Another great test to do is to check the disk IO on the VPS/Dedicated Server, which you can do by running the following command via SSH:Code:
dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
[[email protected] ~]# dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync 16384+0 records in 16384+0 records out 1073741824 bytes (1.1 GB) copied, 2.33085 s, 461 MB/s [[email protected] ~]#
>50MB/s is fine for HDD and >100MB/s is fine for PURE SSD. For those wondering, and just to give you an idea, the example above is a HostXNow VPS Node running RAID 10/PURE SSD.
If the results are any higher than the IO show above (50MB/s - 100MB/s) respectively, then that's a bonus as it's one of the factors whether scripts run fast or not e.g cronjobs for WordPress plugins finish faster.
