I figured that 10GbE was used. Was that throughput to a single client, or was it aggregate at the server? More details on my situation -- I typically see 35MB/sec over my current 1GbE lines. Clients are WinXP32, WinXP64, and soon Win7. Disk rates exceed 500MB/sec (RAIDs). Server is Samba 3.0.2x on Mac OSX Server with XRAID SAN. I would really like to see 80-90 MB/sec with my current setup, which I could reach before XP SP3 (we'll put in 10GbE lines sooner or later). I am seriously considering bringing up a new Linux server running Samba 3.5 for performance and other reasons, since Apple is in no hurry to update Samba in OSX. However, I am by no means an SMB expert, so any advice for tuning either my current clients and server, or the potential new server would be greatly appreciated (e.g., how would I set Windows for multi-issue of SMB requests?). I have implemented the relevant tweaks for Windows clients that I've found in the Samba documentation, but no performance increase was seen. I am also in the enviable position of having a network with no packet loss, virtually no latency, and virtually no collisions, so the usual buffering tweaks don't help....
