We selected them for our project, although their performance was very similar to that of the Chelsio. I did experience some issues of the Myicoms interoperating with Neterion, though I am not absolutely sure whose problem it was. We were looking for bulk data transfer, so I did no testing of small packets. Just 1500 and 9000. In any case, they worked quite well in our application with FreeBSD 8. In the past year the project moved to Linux due to a desire to standardize all systems to a common OS, but they ran reliably and at full line rate with jumbo frames over links that ran from California to Europe and Australia. (Yes, careful tuning was required.) --=20 R. Kevin Oberman, Network Engineer E-mail: rkoberman@gmail.com
