I re-worded what I wrote for clarity, it's an obscure sort of sentence construction. "I don't agree with Jim Keller in that absolute highest performance is found in Infiniband, not only with bandwidth but latency. " I don't agree with Jim Keller who says that Ethernet would be as good or better, in that when you use Infiniband, you get the absolute highest performance from IB, since IB does best on bandwidth and latency considerations.
