Last week we noticed that the default scheduler isn't being set properly in CentOS 7. I haven't checked this for CentOS 6, but it might be worth exploring.
The TL;DR is unless you're running CentOS 7 on a laptop or as a virtual guest, you should probably run 'tuned-adm profile throughput-performance'
I wrote up the full details here -> http://jperrin.org/centos/boosting-centos-server-performance/
Cool. thanks!
I have noticed (without being quite sure what to do about it) that my Centos 7 desktop (six core AMD Vishera) seems sluggish at times, when there doesn't seem to be much running that should be a system hog. I'll see if this change helps resolve that.
Does running the command shown there make a permanent change, i.e., one that survives reboot?
Yes. This command will drop an 'active-profile' file in /etc/tuned that will be used and survive reboots, kernel updates, etc.
