How to test VPS Speed and Performance? Install and Run UnixBench & sysbench
VPS hosting services eliminate many of the problems associated with shared servers including system slowdowns caused by other users on the servers.But when you purchased the VPS and want to know its performance, then you can simply perform the benchmark test yourself.
In this simple article I will tell you the magic command how to find out your server’s disk performance (I/O – write and read speed),CPU performance etc. .These two free tools allow you to conduct quick test on your server to easily find out its general info and performance.
There is more than one way to check the performance available on a VPS Server.If you are looking for great performance and ease of use, then you should look into Following :

How To Benchmark VPS System (CPU, File IO) With sysbench
apt-get install sysbench man sysbench
1 2 3 4 5 6 7
wget http://nchc.dl.sourceforge.net/project/sysbench/sysbench/0.4.12/sysbench-0.4.12.tar.gz tar zxvf sysbench-0.4.12.tar.gz cd sysbench-0.4.12/ mkdir /usr/sysbench/ apt-get install automake apt-get install libtool ./autogen.sh
How to Test VPS CPU Performance
The faster your CPU performs, the faster your server can process tasks. Just use the command(Note that this CPU measure is by no means comprehensive. but it does give an overall look at how CPU-bound workloads will be handled by the different VPSes.)
sysbench --test=cpu --cpu-max-prime=20000 run
File IO Benchmark
IOPS (input/output operations per second) are a metric that are commonly used to measure disk I/O performance.To measure file IO performance, we first need to create a test file that is much bigger than your RAM – 150GB is a good value:
sysbench --test=fileio --file-total-size=150G prepare
Afterwards, we can run the benchmark:
sysbench --test=fileio --file-total-size=150G --file-test-mode=rndrw --init-rng=on --max-time=300 --max-requests=0 run
How to Test VPS Disk I/O Performance
Disk performance is important.High disk IO is important to ensure your server works efficiently and your web applications do not slow down.This script is the one I see a lot in many forums and blogs.Just do the following
dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
hdparm can be used to get/set the disk information, if you don’t have it, you can install by using:
sudo apt-get install hdparm #yum install hdparm
You need to specify which hard disk partition, the first HDD is usually /dev/sda1, the second is /dev/sda2 or /dev/sdb1 etc.
hdparm -tT /dev/sda1
There is a big difference regarding to the disk performance between HDD and SD Card. Remember to remove the file by rm -f test after you finish the test.
Test VPS upload/download speed
We can use Matt Martz python script speedtest-cli to Test VPS upload/download speed.just do the following :
1 2 3
wget -O speedtest-cli https://raw.github.com/sivel/speedtest-cli/master/speedtest_cli.py chmod +x speedtest-cli python speedtest-cli --share
wget freevps.us/downloads/bench.sh -O - -o /dev/null|bash

Install and Run UnixBench
UnixBench is a popular server benchmarking tool,its results depend not only on your hardware, but on your operating system, libraries, and even compiler.This tutorial will cover how to install and run UnixBench on a VPS.
To install and run UnixBench, follow the instructions related to the Linux distribution you are using :
1 2 3 4 5 6 7 8
yum install gcc gcc-c++ make libXext-devel yum groupinstall "Development Tools" yum install libX11-devel mesa-libGL-devel perl-Time-HiRes wget -c http://byte-unixbench.googlecode.com/files/unixbench-5.1.3.tgz tar xvzf unixbench-5.1.3.tgz cd unixbench-5.1.3 make ./Run
1 2 3 4 5
apt-get install libx11-dev libgl1-mesa-dev libxext-dev perl perl-modules make wget http://byte-unixbench.googlecode.com/files/unixbench-5.1.3.tgz tar xvf unixbench-5.1.3.tgz cd unixbench-5.1.3 ./Run
However those two tools are not the only script to perform benchmark but I consider it as the quickest and simplest available.Sysbench is one of the most common benchmarking utilities.
As for UnixBench: if it does encourage you to switch to a new system because it has a higher UnixBench Index Score, you might want to try upgrading your compiler first!
