You're running out of send/recvspace or your ethernet is maxed out.
net.inet.tcp.sendspace: 16384
net.inet.tcp.recvspace: 16384
Try tweaking these values. You should also bump
maxusers/nmbcluters/nmbufs so you're using about 20-30% nominally. Also
make sure you're using full duplex links and you're not seeing excessive
errors/collisions.
I'd have to watch 'systat -vm' to check for some of the more remote
problems ...

Small processes.

Depends on the release... I would not go above 256.
