Re: [Samba] performance problem. big amount of net traffic for file

Hi,=20

I'm working with Jean-Philippe, and the problem doesn't seem to be a buggy =
net=20
driver, as all the packets received by the server seem valid (no checksum=20
error). But of course, we're no windows experts, so maybe in windows the=20
low-level drivers can have an influence with the upper IP stack...

Most (if not all) of the traffic from the XP workstation seems OK, except f=
or=20
this crazy retransmission of the same request (not a tcp retransmission, th=
e=20
paquets have different tcp sequence numbers).
