Hi, Although I use this with Samba 2.2.7, it should apply to 3 (I will find out soon enough :). I found this to be a good setup. I've; sys setup- gbit (non jubmo) 8 port 3ware raid card sw raid on xfs 2.4.20-20.9 (log v2 and s size = 4096) samba setup- socket options = TCP_NODELAY SO_RCVBUF=262144 SO_SNDBUF=262144 max xmit = 65535 read size = 65535 log level = 0 (no comments or non functional lines in your smb.conf file) client setup- regedit so that tcp window size = 128k (google this as I don't want to give you my regedt script for it may incure me supporting it). Although I'd rather have a NetApp and be done with what I call admin nightmares, I do get around 35MB/s which is cool. Krusic Consulting Inc. Network Consulting Services.
