Recently we've been conducting throughput tests on various protocols. The results of the protocols can be viewed at: http://network.ucomm.wayne.edu/benchmark/ So... I guess the real question is this: is it possible for a single SMB file transfer to go faster than 20 Mbps? Is 20 Mbps as good as it gets? We had done tests with 9x/NT4/2K and achieved similar results when TCP/IP is used as the transport. I've include the relevant [global] of my smb.conf files for both systems. I've also tried tweaking the SOCKET OPTIONS, but the largest increase I had seen was ~1.5 Mbps. Any help would be greatly appreciated.
