samba issues? drops?

[Sean Hafeez <sahafeez_(_at_)_zaphodb_(_dot_)_org>]

I have a new install of 3.5 w/Samba installed from the ports. The only 
thing I am using Samba for is to serve files to my AudioTron. I was 
doing this from this same box running Gentoo Linux before. The issue is 
that running the server on OBSD is way to slow. Copying any thing over 
takes ages. The AudioTron skips like mad. Let me stress that this 
worked fine on the same box with the same cables under Linux. I have 
done some testing and here is what I got:

Transfer of 500MB file to and from the OBSD box from a Mac via FTP.

524288000 bytes received in 00:59 (8.39 MB/s)

Trying to copy the same file via Samba up or down takes days.

Is there some know tuning for Samba under OBSD? I have seen that other 
people run it just fine. I have ruled out any hardware issues. Also I 
tested steaming the same file from the Mac via Samba to the AudioTron 
with no issues (The Mac is running Samba 3.02). They all plugged into 
the same switch. The FTP test shows that the NIC is fine. It is very 
much just Samba on this box.  I have tested with and without PF 
running.

I have not used OpenBSD since 3.0 and decided to switch back for this 
server/firewall. I am getting a bit frustrated. Help please! (BTW, for 
those that read about my PF issues I have found that it is the NIC - 
drive vr0. I am buying a new one - Intel- Thanks!) Maybe I should try 
to compile Samba 3.x on this box?

Thanks,
Sean
