Wait a minute; now I'm confused (I'll admit it's not hard to do ;-)
You say FTP performance is not much better (how do you "ftp" to
samba? do you mean smbclient, or ftp to the linux/unix host?). Are
you using the cheesy little DOS-prompt ftp client on the windoze
side? FTP is completely independent of SMB (except they both need
TCP/IP), so if your ftp performance is that bad, it's a more
fundamental problem (and has nothing to do with your samba
configuration). Are you running any other protocols on your
network (other than TCP/IP)?
As for the windoze TCP/IP parameters, I didn't disable them
according to the samba docs (because I need them for DUN). What
solved my initial samba performance/access problem was raising the
RWIN value from 4xMSS (the default in MTUSpeed, as well as other
references) to 8xMSS on the windoze client side (ie, I bumped it up
from 2144 to 4288).
Does this problem happen on all windoze clients, or just one or
two? Are these clients running win95a, OSR/2, win98? Have you
applied any of the M$ updates (eg, vredir, tcp, ip, etc)?
Sometimes the windoze network stack gets corrupted and the only way
to fix it is to remove all protocols/clients and re-install them
(you probably already know this, but it's worth a shot).
What's the performance like when you ftp between two linux/unix
machines? It sounds like it's a problem with something other than
samba. If so, feel free to mail me directly if you want to pursue
it further (I have a little test network at home; maybe I can
replicate your problem...)
Regards, Steve
