No reports, sorry. We did run singe L4Linux instances with ORe on some
100 MBit ethernet cards (that was about 4 years ago) and got very low
drops (<5% if at all) in throughput.

We tested ORe on e1000 as well as a TG3 NIC built into one of our test
machines. Cannot give you performance numbers for that, though.

I don't assume there will be any difference to the influence normal
Linux processes have on the network performance. You will get
performance hits if you run several instances of the L4Linux kernel and
ORe needs to multiplex the physical NIC amongst them, but this is
