which scheduler is better for a server. Should I stay with anticipatory
because I am using an IDE disk or switch to something else because my
system is a server?
That article is before the work began on the CFS/CFQ scheduler. There
has been a lot of improvements made to the CFQ scheduler in the past year.
http://kerneltrap.org/node/8059
CFS and CFQ have NOTHING IN COMMON.
CFS is a TASK scheduler.
CFQ is a BLOCK IO scheduler.
Two completly different fields.
Please stop confusing this stuff, ok?
deadline/cfq/as is block IO stuff
cfs is about 'what app runs next' stuff.
My mistake. Thanks for clearing that up for me.
