[Beowulf] Intel CSA performance?

Intel added a special connection on their chipset to connect
gigabit on some chipsets (CSA). I've been wondering whether
this would offer a latency advantage, since it's conventional wisdom
that PCI latency is a noticable part of MPI latency.
claims that CSA actually hurts latency, which is a bit puzzling.
it is, admittedly, "gamepc.com", so perhaps they are unaware of
tuning issues like interrupt-coalescing/mitigation.
do any of you have CSA-based networks and have done performance tests?
thanks, mark hahn.
