George, FTP is going to be limitted by the speed of your disk. SCP, unless you have crypto hardware, is likely going to be limitted by CPU. I've FTP'd between Linux virtual machines over a real hipersocket on single-IFL z9-109 at over 200 megabytes per second.
Just a note that FTP get is MUCH faster then FTP put.

After following the setup steps in the Hipersockets Red Book transmit speeds using ftp or scp have been disappointing. Either our testing process is incorrect or the configuration is wrong. Does anyone have experience with this environment? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
