SSH Commands To Check The VPS Performance

By | August 17, 2013

Here are some common SSH commands done through putty to check the performance of the VPS

Checking the processor used for the VPS

[abc@vps2 ~]$ [php] cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6

cpu MHz : 3200.539
cache size : 12288 KB
To check the I/O (Input Output ratio) of the VPS [/php]

[php]
[abc@vps2 ~]$ dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out

To check Disk space on the VPS

To check in KB

[abc@vps2 ~]$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/simfs 26214400 11343856 14870544 44% /
none 65536 4 65532 1% /dev
tmpfs 65536 396 65140 1% /tmp
tmpfs 65536 396 65140 1% /tmp
[abc@vps2 ~]$
To check in GB

[abc@vps2 ~]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/simfs 25G 11G 15G 44% /
none 64M 4.0K 64M 1% /dev
tmpfs 64M 396K 64M 1% /tmp
tmpfs 64M 396K 64M 1% /tmp
[abc@vps2 ~]$

[/php]
An automated to do some of this is to use the shell script “Linux server info script” at akamaras.

The output of my VPS is this:

[php]
[abc@vps2 ~]$ sh bench.sh
CPU model : Intel(R) Core(TM) i7 CPU 970 @ 3.20GHz
Number of cores : 1
CPU frequency : 3200.539 MHz
Total amount of ram : 128 MB
Total amount of swap : 128 MB
System uptime : 20 days, 13:35,
Download speed : (3.89MB/s)
I/O speed : 60.1MB/s
[abc@vps2 ~]$
[/php]
