Thank you for making this change, finally.
I'd just like to point out that Baloo is far from the only thing that
uses ionice. mlocate even uses it by default when it's available. I
also use it extensively in backup scripts and other long-running
background operations. I even use it for Dropbox

I installed trusty on my machine which has a magnatic hard disk and a solid
state hard disk. Looking in /sys/block/sd*/queue/scheduler I can see they are
both using deadline.
After installing kubuntu-settings-desktop from trusty-proposed and rebooting I
check /sys/block/sd*/queue/scheduler agai

Hello Rohan, or anyone else affected,
Accepted into utopic-proposed. The package will build now and be
available in a few hours in the -proposed repository.
Please help us by testing this new package. See

enable and use -pro
** Description changed:
[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 schedu
Steve also asked for some testing with Ubuntu 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 -

Likewise, waiting until after 14.10 seems overly conservative.

[09:16:35] OK. How about this for a plan:
[09:17:31] Since it's changed in 14.10 and that's about to get large
scale testing, we wait until ~ a month after 14.10 release to see if we get
negative feedback and if not go ahead.
[09:17:47] In the scheme of 5 years of LTS, that time is a detail.
system administrators can choose a different scheduler if they so wish.
cfq is the kernel default hence probably better tested by everyone in
the world than deadline.
also since a quick web search suggests that deadline only offers better
performance in database/server scenarios I doubt what is s
How would I prove that? Is there something specific you'd like me to
test? We've deployed this in 14.10 for a few months now and haven't seen
any issues, before deploying the same change to 14.10 I asked the Ubuntu
kernel team if we can switch to CFQ and they gave me the green light
saying that it
How do you guarantee this doesn't cause regressions elsewhere?

Super important bug. It can make IO come to a crawl making desktop systems
unusable on rationale media, which in turn makes users unhappy, users complain
to upstream, user complain to us, users complain to users. This is not good. It
makes people waste
