Hello!

This is an old issue that I have seen for many years and it is not resolved
yet. I'm experiencing very high CPU when copying big number of files from my
backup to the HDD on a newly installed system. I'm talking about 300+ GB data
of various types. The issue results in freezing of programs, audio lags when
playing music, unresponsive desktop.
I don't know exactly what causes this problem but I assume it is something in
the kernel because I have this problem since openSUSE 12.1, I've also seen it
on all Fedora versions I've used (17-22), tested on both ext4 and XFS on 3
different machines (HP635, HP ProBook 4540s and my current Fujitsu Celsius H710
- all 3 of them with a different hardware).
