well, if the numbers mean what they appear to mean, this is quite
a dramatic breakthrough: 1.2 us, 25M msg/s. since we just happend to
be talking about "conventional" IB vs Infinipath (1.29 us, 11.3M msg/s).
or is this an example of message aggregation? heck, from the url
above, it might even be counting intra-box messages.
also, I'm sorta amazed people keep selling (and presumably buying)
dual-port IB cards. doesn't that get quite expensive, switch-wise?
