[opensuse] strange difference in up- and downloading from sambaserver
Hi all, I have one server (Suse10.0) that has a great difference in speed when transferring data up or down a samba-share. Copying an iso-file (650MB) to the sambaserver is 10 times faster than getting it back to the PC. Since most traffic is getting data from the server, this poses rather a problem, users are complainig about it. This happens with WinXP clients and also when I do this with my 10.1 laptop. When i do scp with my laptop on the same iso-file, I still have a diff of a factor 6. Not as much as when I use smb, but still too much to be good. Somebody have any idea where I have to start looking, and what tools to use for this? I already did the documented tweaks on smb.conf with socket options, this does not help. I do not directly suspect samba, althoug here it is the worst, because the speed-diff is also there with scp. -- L. de Braal BraHa Systems NL - Terneuzen T +31 115 649333 F +31 115 649444 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Well its good you don't directly suspect samba, because you more or less proved it was more generic than that. How is it connected to the other machines? In house network? Wide area network (internet)? This sounds more like a network problem than a samba problem but you give is precious little info about your network. -- _____________________________________ John Andersen -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

In house network with a switch, 100Mb. The owner already swapped the switch for another one, but I have not seen it yet, nor did I do my copy-test after this with the cd iso. I will be there this afternoon, and check it out again. Owner says, that swapping out the switch did not help. There are about 6 to 8 PC's attached (some laptops occasionally).

Could be as simple as the server busy with request to download from the rest of the PCs, so network busy in one direction. - -- Cheers, Carlos E.
