Summary: Very unstable "speed meter" while copying large files
Product: kde
Version: unspecified
Platform: Gentoo Packages
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
AssignedTo: unassigned-bugs at kde.org
ReportedBy: apopatos at gmail.com
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.
