Open Source Linux system benchmark software

Question

How can I run a system benchmark in a Linux installation? I'd like to do a full test with the core system functionalities like:

• CPU performance
• Memory performance
• Disk / IO performance
• Network performance

Is there any Open Source tool that I can run in a server and collect benchmark data?

Answer 1

Check out

http://openbenchmarking.org/

They have a lot of good information about Open OS Benchmarking.

Answer 2

I find sysbench pretty useful.

On my cloud machines, I often run:

for i in cpu threads mutex memory; do
        sysbench --test=$i run
done

Note that there are many, many test options, and two more modes that require a bit more setup (fileio and oltp).

I use this to determine the relative speed of various instances I launch with my cloud providers.
