Ofed 1.2 rc3 is running IPoIB slower that rc2 or earlier

I use to get ~800MB/sec no tuning and now I get ~650MB/sec ??

Ideas??

Not specific to IPoIB, but whenever something like that happens to me I start with things like:

*) CPU utilization - did that and the netperf (assuming netperf) service demand increase?

*) packet losses?

*) change in MTU?

*) change in interrupt behaviour by the I/O card? (ie did netperf TCP_RR change much?)
