Samba speed (too slow)
Hi all, A while ago (a few weeks) I installed a sambaserver on a Suse 8.1 box. I thought it was ready for "production" but I found a problem. I managed to get winbind autenticate the users, but the response of making a networkconnection with Win-clients is rather slow. Today I tried to copy a file of 162Mb on it and this took about tree quarters of an hour. Any suggestions to diagnose this problem ? B.T.W. the switch (=hub-like device) indicates the NIC runs at 100Mb. TIA -- Met vriendelijke groeten, Koenraad Lelong R&D Manager ACE electronics n.v.

The last time that I ran into this particular problem was because the network card couldn't handle the sustained transfer rate and was dropping packets. Replacing that network card with a network card that used a different chipset/driver made the problem go away. Try replacing the network card with the same modal since it may be only that the network card had gone bad. If you get the same results, try a different network card that doesn't use the same chipset/driver. This may or may not be the solution for your problem. Christopher Reimer

Just a thought. As we are looking at the network card, we should really look at the whole link. I'd also try swapping the connection to a different channel on the switch. regards Vince Littler

I am tossing this suggestion out only as something to try... and it won't take much to try. I once had a similar problem with Samba under Linux... where transmitting a large file would cause the line to slow and then disconnect. I was finally given the following to try: In /etc/samba/smb.conf, make your 'socket options' as follows: socket options = TCP_NODELAY SO_RCVBUF=32768 SO_SNDBUF=32768 It can't hurt... and it might help. -- +----------------------------------------------------------------------------+ + Bruce S.
