Yes, there are figures for PVFS performance over Myrinet - check the PVFS web page - they are in some of our papers - or talk to Rob Ross he has up-to-date

Those figures are for PVFS over TCP/IP over Myrinet.  PVFS was written for
TCP/IP and won't run over anything else.  At the time the project was
started SCI wasn't really a player yet.

PVFS2 will be protocol independent.  We already have the network transport
mechanism (BMI) working and running well over TCP/IP and GM(Myrinet).  It
should be portable to VIA and SCI.
