Probably something for Illumos, but you guys may have seen this or may like to know.
I've got a 10g connected Xyratex box running OmniOS, and I noticed that no matter how many streams (1, 2, 3) I only get 100MB/sec write throughput and it just tops out. Even with 1 stream. This is with the default lzjb compression on (fast option). I turned off compression and have 2 streams running now and am getting about 250-600MB/sec in aggregate. Much better! The compress ratio was only 1.02x - 1.03x so it's no great loss on this data. I just thought the 100MB/sec speed limit was interesting.
