I don't have a full Ubuntu filesystem in front of me right now, but running on a maverick/xfce-based linaro fs, I still observe some slowdown.
By default, mkfs.ext4 (for example) runs at +19 nice while gparted is making an ext4 filesystem on my SD card. Building the filesystem typically takes approximately 26 seconds in this configuration. renicing to -19 or SCHED_FIFO, building the filesystem is quicker - about 21 seconds (which is close to the time taken to run mkfs.ext4 directly.) The progress bar animation style has changed since I originally reported the bug (or xfce differs from the default gnome theme on this) - with xfce I now get a short bar sliding back and forth, instead of a full- width animated bar. This may affect the gparted/Xorg CPU load. The performance delta will vary between devices depending on memory bandwidth and bus contention etc. In my case, I don't seem to get the same amount of slowdown which I remember observing previously in Jaunty... but it's not the same software or hardware in this case. I suggest that mkfs should not be run at positive nice on any platform - do you know what is causing this?
