Description Apopas 2010-01-21 04:25:55 UTC

Version:            (using KDE 4.3.4)
Compiler:          gcc-4.4.2 
OS:                Linux
Installed from:    Gentoo Packages

I have two hard disk drives. One is formatted with XFS and the other one with EXT4.

Whenever I copy a large file (i.e 4GB) from Ext4 to XFS, the speed meter of KDE acts like a cardiogram, with a speed from 80 MB/s to 25 and vice versa. Finally the copy time is correct and about 58-60 seconds.
When I copy from XFS to EXT4 the meter is stable from 67-70 MB/s and the total time is still about one minute.

I have not tried it with other filesystems, but it seems the "speed meter" is very unstable while reading from EXT4. It doesn't seem to affect the copy action though.

do you reproduce with kde 4.4.4 or 4.5beta ?

Comment 2 Apopas 2010-06-09 08:25:01 UTC

I have not tried it with 4.4+
