Hi,
I made a quick add-on KMP for BFQ I/O scheduler that has been posted recently to LKML: https://lkml.org/lkml/2014/5/29/411
If you have a problem regarding I/O and desktop latency, this might be interesting.
The KMP is found in OBS home:tiwai:bfq/bfq repo. It's currently built for openSUSE-FACTORY, openSUSE-13.1, SLE12 and Kernel:HEAD kernels.
After installing the KMP, load bfq-iosched kernel module, and change the scheduler like: # echo bfq > /sys/block/sda/queue/scheduler
If you want to make BFQ as default from the beginning, do like below:
- Put "bfq-iosched" in $INITRD_MODULES in /etc/sysconfig/kernel - Run /sbin/mkinitrd once to rebuild initrd - Add a boot parameter "elevator=bfq"
Then the BFQ module will be loaded automatically and used as default I/O scheduler at the next reboot.
Have fun,
Oook, installed it, made it the default.. desktop applications appear to respond from slightly to noticeable faster. No crashes, oopses or babies dead have been observed. Only a very small insignificant response time improvement to things like browsers/email clients that obviously at startup perform a bunch of activity bound to the speed of the network instead of the disk. -- Cristian "I don't know the key to success, but the key to failure is trying to please everybody." -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
