http://bugzilla.opensuse.org/show_bug.cgi?id=1112824 http://bugzilla.opensuse.org/show_bug.cgi?id=1112824#c102 --- Comment #102 from Takashi Iwai <tiwai@suse.com> --- Quickly looking at the logs of comment 97, the main differences between two kernel configs are: CONFIG_NO_HZ_FULL=y for Fedora CONFIG_NO_HZ_IDLE=y for TW CONFIG_PREEMPT_VOLUNTARY=y for Fedora CONFIG_PREEMPT=y for TW CONFIG_SCHED_AUTOGROUP=y for Fedora CONFIG_SCHED_AUTOGROUP=n for TW CONFIG_SLUB=y for Fedora CONFIG_SLAB=y for TW The last one is unlikely influencing on the performance, though. The rest are subtle drivers and debugging configs. So I'm building a TW kernel with the config changes above to follow Fedora in OBS home:tiwai:bsc1112824 repo. The build should finish in an hour or so. Please give it a try and see whether if this really improves things as advertised here. -- You are receiving this mail because: You are on the CC list for the bug.
