Test Between BNL and BU.

Tuning on Oct/30/2007

Network test from BU to BNL before network tuning.

The test from atlas-g01.bu.edu to BNL

Since there is a symmetrical performance between data from BU to BNL and from BNL to BU. 
There is a wire speed from BNL to BU. But the performance is really bad from BU to BNL. 

We used the UDP test from BU to BNL:
