the em0 segment doesn't work, bge0 connected to the dc1 segment or
iwi0 (also on the dc1 segment) works.

Are you using IPv6? IPv4 appears to work just fine.

Well... you're going to get a lot more packets through (likely) if
you turn on polling, but keep in mind that your low priority "soaker"
process will no longer be accurate.
Seeing bytes/packets decline and cpu stay the same is the same failure

Different motherboards have several orders of magnitude different

Polling (as others have mentioned) roughly doubles the throughput of a

Further in followup to the ip_fragment() bug, at the crash, off =
