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.
