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 Dan
