Noone changed the IPv6 version.

The syncache already seems to do it for both v4/v6 (common code).

Can you try changing it to < sb_max) for IPv6 as well and see if
things work (better) for you?

I changed it, and that worked like a dream. Now I get basically the
same throughput with IPv4 and IPv6.

That sounds great! :-)


 There are of course still issues
like lots of IPv6 tunnels that add extra latency - but that's not the
fault of FreeBSD.

Anyway, thanks for your work. Below is a context diff (against 7-STABLE
cvsupped last night). Do we need a PR to get this into FreeBSD?

No, not even the context diff would have been needed;-)  I'll commit
it as soon as I find a few quiet minutes and a src tree;-)
