The file size that I tested was 500MB. While the backup is running at 11 MB/sec I used FTP to send another large file down the same pipes and it transfered at 49 MB/sec. So I know that the pipes between server and client will handle the load.
I have adjusted the TCPWINDOWSIZE to 64 on the server and 63 on the client according to the Tuning Guide. I also increased the client's TCPBUFFSIZE from 16 to 32. When I backed up on the 100MB network we were seeing 7-8MB/sec, so we have increased performance a little. There is no client compression. Thanks for all of your input. DW
