We've focused on SDP and MPI performance so far on RHEL4 U3 x86_64.
Some bad news:

*	MVAPICH MPI small message latency is slightly worse across the
board, as measured by OSU latency benchmarks.  For example:

	*	Lion Mini SDR: small message latency up from 3.43 usec
to 3.53 usec
	*	Cheetah SDR: small message latency up from 3.57 usec to
3.73 usec

*	SDP throughput worse and small message latency worse than rc4.
For example

	*	SDP small message latency worse than IPoIB now
	*	Lion Mini SDR: throughput dropped from 7.24 Gb/sec to
6.45 Gb/sec
	*	Lion Mini SDR: latency grew from 17.5 usec to 30.0 usec
