By big I mean 100s of kbytes. I thought that this class of CDF
computation, which uses a lot of memory, also does quite big transfers
along the interfaces between the nodes.

I agree with you that real application benchmarks are a fine thing.
However, this one only has 2 datapoints for 1 application at 1 data
size+node count with a potentially bogus MPI implementation, so it's
bit hard to interpret.

Never fear, there are a half-dozen vendors selling 10 gbit TOE cards.
And nary a benchmark to be found.
