But it's running at gen1. I strongly suspect that the benchmark case was
gen2 (since the ixg is capable of it).
gen1 vs gen2 is 2.5 Gb.s bs 5 Gb/s?
Gen 1 is capable of only 2.5GT/s (gigatransfers per second). Gen 2 is
capable of up to 5, but isn't guaranteed to be 5. Depending on how
chatty the device is on the PCIe bus, I think 2.5GT/s is enough for
something much closer to line rate than you're getting.
