That seems to be where most of the performance gets lost. Just add "slub_debug=-' to your boot line or /etc/grub2.cfg. kevin signature.asc Description: PGP signature -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
Re: Rawhide dead slow on my laptop
It has a Intel 2nd generation video controller (sandy bridge family) and the driver is i915 which should be the less problematic driver I think. -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test

What are your X settings? If X is consistently high then I would suspect the video driver. I have seen the same behavior using nouveau under 3.9 kernel. I have *not* seen that behavior using nvidia under the 3.9 driver but I do have other issues using nvidia (like machine hangs and X crashes).

Rawhide dead slow on my laptop
Hi, I don't know where to start for debugging but current rawhide on my SandyBridge laptop is barely usable. Even a window switch takes 1-2 seconds. I looked over powertop and top outputs, load average when idle (even no gnome-terminal, ran the commands on VT) can be between 0.8-1.1. Xorg is generally at the of top output, 30-40% CPU usage on average. I also see some irq related stuff for iwlwifi in top output. I was passing enable_rc6=0 to i915 but removed that but that didn't help too. Is there a known issue with 3.9 kernel that you are aware of? What should I investigate further before opening a bug in bugzilla?
