Slower data transfer rate in KDE v GDM

[jos180]

I have a FC13 box that has both Gnome and KDE sessions installed.

I have noticed on the KDE session that data transfer rates are slower than when I use Gnome.

In Gnome, I can transfer files between my FC13 machine and my Ubuntu 10.04 pc at a rate of 6.5 MB/s (52 Mb/s if my maths is correct), but in KDE the rate is only 3.5 MB/s (28 Mb/s).

"ethtool eth0" shows my NIC speed as 100 Mb/s. Obviously I am not hitting anywhere near that speed in either session, (a separate article may be happen in the future to address that), but I am curious as to why KDE is that much slower for file transfer.

I assume that by GDM you actually mean Gnome desktop environment. GDM is the login manager for Gnome, such as KDM is the login manager for KDE.
On to your problem. One reason may be that KDE has a different network manager than Gnome. However, there are a lot more differences between KDE and Gnome.

Thanks for pointing that out - duly edited to avoid further confusion.

I realise that there are lots of differences between Gnome and KDE. As much as I prefer the look and feel and the extra funtionality of KDE, if slower data transfer is a factor of KDE I guess I'll have to switch back.

Should have said earlier that the data transfer is being doing via samba share and File Manager.

I have found a workaround (thanks to a comment by Mike1 on freenode irc) and that is to mount the share rather than using Places in the file manager and then transfer the files via terminal rather than the gui.
