Nautilus SMB share extreme slow

[Markus Kolb]

Hello,

why this Nautilus SMB sharing stuff is so extreme slow.
I wait minutes (now 5) to see a file list from a samba server.
In this directory of the share are 2383 files and with MS Explorer I see 
this filelist in maximum 5 _seconds_.
I can not believe that this is only because of a not so optimized 
implementation in Nautilus.
Do you have any ideas what can be done?

Thanks.
Markus
