Dual haswell xeon cpu. 4.8.4-4, NUMA and MuQSS 116 enabled. 0 issue so far and great performance.

I was one of the persons who had issues with NUMA on an AMD FX 8100. About 6 months ago I changed to i7 6700 and disabled NUMA. No issues so far. I did had btrfs corruption with linux-ck early MuQSS versions (v110 I think) so I was a late adopter but now running pretty stable for days. I think the NUMA issue were related to AM3+ socket.

I'm running linux-ck with NUMA disabled since about two weeks. I haven't yet experienced any problems with my Skylake CPU.

@QD - It's a small increase using a make endpoint in my experience (see the flyspray I note in the PKGBUILD comments). It could be that other endpoints reveal more substantial gains as well. In any case, NUMA is really for servers with multiple sockets; it has no point on a single socket motherboard is my understanding. Linux-ck had it disabled for a long time until some combination of upstream/BFS + NUMA disabled was believed to be responsible for problems which is when I disabled the code to disable it. Now that MuQSS has replaced BFS, this may not be the case any more. Several users have posted to the AUR reporting stability with it disabled as is my experience as well.

How much of a speed increase does disabling NUMA actually give, anyway? I've never really felt the difference.

Greg just tagged 4.8.5-rc1 and has it scheduled to release on Friday/noon UTC[1]. We can give disabling NUMA a whirl in 4.8.5-1 if there are no reports linking this setting to bad behavior with MuQSS (I am not experiencing anything bad on my Haswell).

I've been running linux-ck with NUMA disabled since you added that option back to PKGBUILD. I've had 0 issues so far.

I can but I would like to get some additional feedback from others who build with NUMA disabled since it caused problems in the past. I too have it disabled on my workstation without ill effects. Can other AUR users please comment. If you have NUMA disabled, are you running a stable 4.8.4-4?
