I just ran a test from one local box the another on a 100Mbit link and the
fastest transfer OI got was 10MBytes/second but most were between
1MBytes/second and 4MBytes/second.

Pardon the stupid suggestions but

- Did the test you run with iperf, was that a bi-directional test,
 are you sure you weren't testing your inbound speed at ~700KByte/s
 rather than your outbound speed? With most connections, inbound
 speed is several times faster than outbound speed.
Not stupid question me stupid,  I only tested it one way.
I guess I just assumed iperf was testing both up and down.
I didn't have remote access to the source servers firewall, so I had iperf listening on the distination server.
Monday I'll run the test the other way.
- Do you know what sort of bandwidth your "supposed" to have from your
 ISP?
source server business DSL 1.5m down / 878k up
distination server T1 colo at a large ISP.

Sounds like I'll be stuck with the tranfer rate I'm getting.
Thanks Nate
