Make sure you've CVSup'd the latest samba port. On 9/24 patch-ah was added which makes a mod to lib/util_sock.c to resolve this problem on FreeBSD machines: Here's the log description of the patch. It seems to explain exactly your problem, but you didn't give enough info about your samba port installation to tell whether you got this patch or not. ----- start log msg for patch-ah ----- revision 1.1 date: 1999/09/24 04:29:42; author: cpiazza; state: Exp; Add a patch to fix a problem with very low write speeds with samba on freebsd. Following is description made by one of the Samba developers: "The problem is we switched to using recv() with the MSG_WAITALL flag instead of read(). This makes Samba faster on most systems. On FreeBSD it causes a massive slowdown and I don't know why. To fix it, change the definition of MSG_WAITALL to be zero in lib/util_sock.c and recompile 2.0.5a. I'm hoping someone from FreeBSD will get back to me with some explanation. Regards, Jeremy Allison, Samba Team." This problem where observed by almost all samba-2.0.5a users and typically it led to 10-20x decrease in write speed.
