Testing diffs, especially those related to kernel locking, and reporting back on them can help. Running -current, updating fairly often, and reporting on problems seen (with a good date window for when they were first seen, or even better bisecting to the individual commit if possible) can be useful too.

(the limit is more to do with packets per second than speed). "do the upgrade to 10GbE" isn't specific enough as to what's needed to be able to give much usrful advice.

Any experience with 10Gbe?
I'm supporting a small business who needs more bandwidth due to the work-from-home situation. They've asked me to help them do the upgrade to 10Gbe. I'd preferto keep them on an OpenBSD router, since I love how liuttle maintenance it needs, but I can't find any accounts of someone actually managing to get close to line speed above 1 Gbe. I don't want to just buy expensive hardware and hope that it works. Has anyone here been able to get close to 10 Gb/s networking with OpenBSD? I don't need to be able to have more than a few pf-rules. -- Nicholas C. L. Ipsen
