[Impact]
Using deadline causes performance regressions in Baloo. See bug 1310402 for an example.
[Test Case]
* Upgrade kubuntu-settings
* Reboot
* Make sure boot completes successfully
* Make sure IO scheduler is set to CFQ on boot in case you have a HDD : cat /sys/block/sd*/queue/scheduler
[Regression Potential]
None that I can think of, deployment has been successful on Utopic |
[Impact]
Using deadline causes performance regressions in Baloo. See bug 1310402 for an example.
[Test Case]
* Use Kubuntu trusty until it slows to a crawl
* Upgrade kubuntu-settings
* Reboot
* Make sure boot completes successfully
* Make sure IO scheduler is set to CFQ on boot in case you have a HDD : cat /sys/block/sd*/queue/scheduler
* use it and verify it no longer slow to a crawl
[Test Case for Unity]
- installing an Ubuntu precise desktop with unity7 (which I believe was the
last release using cfq by default) and the .0 kernel (3.2.0)
- using the system for a bit to try to reproduce the original problem -
application windows becoming grayed out by the WM under normal usage,
indicating that the app is not responding
- changing the scheduler to deadline and testing to see if the problem
persists or resolves itself
- upgrading to the trusty backport kernel (linux-image-generic-lts-trusty)
- verifying that the desktop behaves correctly with the default deadline
scheduler
- changing the scheduler to cfq and testing whether the original problem
recurs
[Regression Potential]
None that I can think of, deployment has been successful on Utopic |
