tuned-adm Latency-performance Profile Settings

Posted by AG2011 on 2011/12/7 15:31:17

Hello!

Looking at documentation for power management and specifically tuned-adm latency-performance profile states the following:

latency-performance
a server profile for typical latency performance tuning. it disables tuned and ktune power saving mechanisms and enables sysctl settings that improve the latency performance of your network I/O.

My question is - what exactly does this profile apply to network settings to improve latency on Network I/O? I looked at the settings in /etc/tune-profiles/latency-performance/sysctl.ktune at it contains only this line:

# ktune sysctl

It does not look like it applies anything to sysctl.

Thanks!
