I have several long running benchmarks (SPEC CPU 2006 benchmarks) to run on a Linux server.
The server is running Gentoo Linux with a Linux Kernel 3.6.11.
I saw some big differences between different runs and I'm thinking that it could be some problem with my configuration.
I'm the only user of the server.
I have already done several configuration changes:
- I have disabled the CPU frequency scaling feature of the kernel.
- I have removed all cron jobs
- I made sure that there were no frequency scaling in the BIOS
Is there some others things I should configure/disable/enable in the kernel or on the installation ?
I do not need to make the server faster, but I want to make sure that the benchmarks are not encountering pertubations
