Script to test CPU performance

ckissi

Hello,

Anybody can suggest bash script for CPU performance test, e.g. something gzip based.

thanks

WSS

Why would you use gzip to test the CPU abilities rather than something capable of threading or actual-real-work applicable?

#!/bin/sh
tar cvpf - /dev/random | gzip -9 > devrandom.tar.gz

Not bad, I could add some network locations

Fork bomb that CPU to hell and see how fast it really is. If it resists an hour in that logical chaos, than it should be fine.

My personal view is that this is an incredible dick move- but if there are no ulimits set, welp- there soon will be.

Add all mirror location from Leaseweb

mirror.nl.leaseweb.net & mirror.de.leaseweb.net & mirror.us.leaseweb.net
