Has anybody else noticed some major improvement within the last few
days? I am running on kernel version 5.15.0-47-generic and have now been
running my laptop for 6 days without needing to reboot, and everything
suddenly seems to keep running smoothly. I previously had to reboot
every second day to have the machine running anything close to
acceptable.

My last reboot was on the 21st, and between the reboot on the 19th and
that I can see the following updates in /var/log/dpkg.log:

2022-09-19 10:37:40 status installed gcc-12-base:amd64 12.1.0-2ubuntu1~22.04

I have no idea what can have made the difference other than these. The
current kernel is from September 1st, so that in itself definitely
didn't solve anything.

Title:
  massive performance issues since 22.04 upgrade

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi,
  After upgrading to 22.04 i had to fight with massive performance issues.

  Browsers appeared to hang every other minute, youtube videos being
  laggy and hang in between, applications in a virtualbox VM where slow
  and also hanging every other minute to a level of not being useable.
  On a pretty recent and powerful system just 2 years old.

  I noticed CPU jumps in top, but also somehow thought it could be a graphics 
issue so invested some time installing nvidia drivers properly.
  Also I wondered if it might be the lowlatency kernel I normally use because I 
do audio stuff, and switched to generic. But nothing helped.

  ThenI had the idea it could be a kernel/scheduler issue because the
  system wasn't always slow, but it appeared certain things kept hanging
  when other processed had a lot of cpu for a few seconds.

  So I got a recent mainline kernel, configured it with my last running
  config from 21.10 before the update, made the debs and installed them,
  and now can tell that a mainline kernel 5.17.7 with all the dkms
  modules that i had before which got compiled automatically at
  installation brings back a "normal" performance.

  I can browse the web, run multiple youtube vids at once, even in
  another browser, have thunderbird running, and a virtualbox machine
  open with another browser for some web app testing and everything runs
  fine and smooth, no lagging.

  Not sure yet what the real reason is - either the kernel version, or a
  patch in the ubuntu version, or the 22.04 kernel config so far, or
  some configuration made in 21.10 that isn't good with 22.04 and it's
  kernel anymore.

  I will go ahead tomorrow and see if I can build a vanilla kernel with
  the config from the ubuntu 22.04 kernel and "make oldconfig", then I
  will be able to tell if only the config is making the difference.

  Please let me know of there is anything I should test to further
  analyze this issue, or any ideas I can try to solve it without having
  to run a mainline manually installed kernel.

  Thanks.
