Well, I get about 0.9MB/s using scp to copy from the original file to localhost. The overhead on both ends of the transfer undoubtedly explains the (slightly) lower transfer rates. *Sheesh* OTOH, I recall that people are using this level of hardware as routers, and I recall them getting about 30Mb/s (or 4MB/s) through them. Is there really that much overhead with scp? Frank
