[Samba] Speed problems after an upgrade to 3.0.10

[Arnaud Goulois]

Hello,

Since an upgrade of Samba to 3.0.10 two weeks ago, i've got some speed
transfer problems. I have a Debian server with Samba 3.0.10 and a
client with Win XP SP2 (both are plugged on a 100Mbps switch). When I
transfer file from the server to the client transfer rate seems to be
okay but sometimes et falls down (which causes freezes when i'm
reading music or watching movies) but the worst is when I try to
upload files from the xp client to the samba server, it takes 30min to
transfer 300MB!!!
I have try everything I found on the net. I've try all possibility for
'socket options' on smb.conf but no one has worked :'(
I also tried to downgrade (to 3.0.8, 3.0.7, 3.0.6 and 3.0.5) but this
didn't fix my problem
I don't think it's a network problem because FTP works perfectly
between theses two machines...
I put my smb.conf at the end...

Thanks for your help

Arnaud
