All, Thanks for all the replies, but mainly to John Garner for sharing some performance figures he had done himself on this. The problem is with the performance of the T2000 itself on a single thread app. When you ftp to the server, the ftpd is obviously only one thread, and the system could only pull in up to 25Mb/s through the NIC. If you launched another ftp session at the same time the total ftp traffic increased to 50Mb/s, this continues until you saturate the interface (running at 100Mb/s FD). But a single thread _can't_ utilize the full 100Mb. Which frankly sucks! My Ultra 10 can do that. You really do have to be careful with these systems, and ensure your workload is going to fit well with the strengths that this box undoubtedly has.
