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.
I feel the gnome has become a bit more responsive, but I tried the free Nvidia drivers, it could also be optimization nouveau driver in the kernel, This should be checked on the Intel graphics, unfortunately I have no such opportunity now -- You are receiving this mail because: You are on the CC list for the bug.
