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.
