Hello,

We have 3 pc's here running Linux, each has a 100BaseT card in it. 
Currently we have many test programs sending and receiving data.  They
all are experiencing this problem.

In the simplest program, we are sending a vector of complex floats.  The
vector size varies, usually we have it set to be 4096.  The sends and 
receives are fine - both sides sending and receiving correct data.  
The data rates are extremely important to our project so the faster the
better.  

We run the programs to send and receive these vectors between 2 pcs and
we do nothing else so as not to slow anything down at all.  BUT (here's
the kicker) We've found if we move the mouse, it speeds everything up.
We get better data rates and the program finishes faster.  

We've exited out of Xwindows and tried it at the prompt.  Same thing.

Any ideas on how to get the mouse out of the picture?  

Thanks,

Misty
