If you are buying hardware right now, you might try Myricom 10GbE, that's
the first 10gbe driver that isn't running under biglock. Right now there
is a lot of work going on at and near the network stack to both improve
implementation performance and add concurrency.

 Our link between our Primary and DR DCs needs more than 4.2Gbps,

Which version are you running now?

Peeking at /usr/src/sys/net/hfsc.{c,h} appears to indcate that hfsc
(which is what the 5.5 and later queues uses) has 64 bit values where
it counts.

64 Queue Sizes in OpenBSD 5.8

[Andy Lemin]

Hi,

Is their any news whether we'll have 64bit PF queue sizes soon?

Our link between our Primary and DR DCs needs more than 4.2Gbps, but we
cannot shape traffic above this due to the 32bit queues.

Simply we need to impose shaping to ensure the CDR is not breached. We
really need to upgrade the CDR to 6Gbps, but the penalties for taking our
95% percentile above the CDR are very expensive.

Cheers, Andy.
