Very good, but only worked for Intel e1000 (IIRC)

Worked well, but some of my more recent tests with
Chelsio and Mellanox 10Gbe were mixed using Open-MX.

Many of the 10Gbe (and above) vendors seem to
be paying more attention to performance than
before. I like that for my small scale Limulus
boxes I can get 8-9 usec latency using tcp,
which provides a great performance bump over old 1 Gbe
HPL increased from 480 to 658 DP CPU GFLOPS using 4
Skylake procs). I should have my Hadoop terasort
numbers by the end of the month as well.
