2.0.6pre3 compiles and installs under FreeBSD 3.2-RELEASE; however, throughput
from an NT 4 SP6 workstation with domain security and only TCP_NODELAY
as a socket option is clocking around 200K/sec for large files (65MB).

I used the patches from 2.0.5a with the MSG_WAITALL patch included as
patch-ah.

My experience with samba/FreeBSD suggests that 3.3-RELEASE won't be much
different.

Hardware is 2 x PPro200 with  single CPU kernel;
Adaptec 2944UW/3 Quantum 9GB Atlas II wide diff drives (clock
9MB/sec using bonnie), Intel Pro100B, full duplex 100Mbit switch between
client (PII/400 3Com905B, 128MB RAM) and server.

I've never gotten samba 1.9 or 2.x to run with SMP; copying large files 
inevitably crashes the server connection, with no errors in either the
samba or system logs.  

The behavior I'm seeing in xperfmon++ v3.0 suggests that there is a problem
in syncing writes from the client to the network and from the network to
the server, i.e., disk traffic on the host is very bursty with peaks over
1MB/sec but with no disk traffic much of the time.  The benchmark program,
TESTNET 2.24, writes 65K blocks 1000 times sequentially to the mounted
server share.

netstat -i shows 3 input errors in 6 million frames, 1 output error in
100,000 frames.  NFS mounts of this server clock around 3MB/sec.

Samba logfiles show nothing, other than the usual "call_nt_transact_ioctl:
Currently not implemented." which shows up every time 2.0.5/6 starts.
