Tunning for performance (was: tar's default block size & shoe-shinning)
2006-06-29 11:39:40
Hi all,
I haven't yet solved my performance problem but I
wanted to share the following URL with anybody who is experiencing the
same problem as me:
http://www.redhat.com/magazine/001nov04/features/vm/
It introduces a lot of Linux's virtual memory configuration
parameters (/proc/sys/vm/...).
In fact, I just noticed that kswapd and kscand are
eating a lot of CPU% when amanda is running... Maybe that's related...
I've already set the "noatime" flag to my
filesystem, and changed my logical RAID drive's settings to "READAHEAD"
and "CachedIO". But none helped.
Regards,
Cyrille
