Likewise, a lot of optimization work has been done to improve Linux
TCP / networking performance (specifically latency) by people
doing Beowulf cluster stuff. My understanding is that one of
the main reasons Linux took off in the HPC world is exactly
because it's open-source nature allowed the researchers to
optimize the kernel and TCP stack to get the performance they
needed.

So a google search along these lines:

might turn up something useful.


HTH...
