Chuck, that's certainly true with single stream TCP, but on these high capacity links who is really saturating them with a single stream?
Please not that my tests with 20-stream TCP are pretty close to equal to UDP tests, and I suggest that 20 streams or more is a reasonable approximation of real-world traffic. Of course that doesn't come close to the thousands of connections with varying packet sizes running over a normal pipe, but we don't have the tools to simulate that.

Many times the TCP traffic is usually less (sometimes 30%+ less) than the UDP tests. Jayson are you also basing your tests on UDP? I have multiple links that perform similar on UDP as well...I think you will find though that more of your traffic is TCP and that is a major impact on the performance of the link.

The limiting factor here was the RB411. If we had been using an AH I suspect it would have been a lot faster. You need really, really, good signal levels to make this work, and virtually zero interference. That combination is problematic.
