Great, thanks. I tried it out today, but the performance wasn't exactly
what I had expected.
This is a dual port card, so I bridged ix0 with ix1 and ran iperf
between two hosts through the card. The hosts were connected with
1Gbase as I have no other 10Gbase cards.
It only got up to about 450 Mbit/s (standard TCP iperf test) and there
was an unbalance between ix0 and ix1 when it came to interrupts. ix1
only got up to 4000 intr/s whereas ix1 got up to 13000 intr/s (when
monitoring live with systat vmstat). The CPU intr usage was around 50-60%.
Could this possibly be related to the ppb problems we've seen with em(4)
cards?
