sysprof profile of the slow workload

I use a simple graphical tool called "backintime" for backup tasks, which only stores modified files and creates links for unchanged files.

Deleting my backup-disk using "rm -Rf backup" takes a lot of cpu time (mounted with compress), after a few minutes I decided to reformat the whole drive.

Sysprof profile is attached.

Closing, if this is still affecting you on a newer kernel please reopen.
