How to benchmark a linux server using UnixBench

Unixbench is the most used benchmarking software tool. It can measure the performance of bash scripts, CPUs in multithreading and single threading. It can also measure the performance for parallel taks. Also, specific disk IO for small and large files are performed. You can use it to measure either linux dedicated servers and linux vps servers, running CentOS, Debian, Ubuntu, Fedora and other distros.

benchmarking a linux server with unixbench

It is based in the BYTE UNIX benchmarking algorythm, which has been updated oftenly over years. It uses the hi-res time functions form Perl, and calculates the time difference between the beginning and the end of such testing processes.

 

CHEAP WEB HOSTING

Preparing the server

For CentOS

yum -y install gcc gcc-c++ make libXext-devel perl perl-Time-HiRes
yum -y groupinstall "Development Tools"
yum -y install libX11-devel mesa-libGL-devel perl-Time-HiRes

For Debian

apt-get install libx11-dev libgl1-mesa-dev libxext-dev perl perl-modules make

Now, download and execute Unixbench

yum install zip unzip -y
wget https://github.com/kdlucas/byte-unixbench/archive/master.zip
unzip master.zip
cd ./master/byte-unixbench-master/UnixBench
./Run

Here’s a sample output, as we tested the performance of a vps server from Copahost:
