Tunning Freebsd for clustering

[Emanuel Marufo]

Hi everybody:

I recently work with mpi on FBSD 6.2 and Centos 4.4 on the same hardware.

2 Woodcrest dual core 3Ghz
2 GB RAM.
150 GB SATA disc.
etc, etc.


My tests, about network and hard disk transfers, say Centos is faster
than FBSD.

My questions are, how can tunning FBSD to upgrade the performance for
clustering?. And why Centos do have better performance?.

NOTE: The two tests on the fbsd was better are floating point
operations and recursitivity, i was impresed with a better managing of
it.
