On this machine I run a program which simulates many (~150) simultaneous

Wow, much useful feedback. Thanks.
Terry, your general formula for nmbclusters per connection is pretty
much what I am looking for. Great stuff.
Frankly, it sounds like your application is bad; does it limit
itself to 150 connections, or is it trying to make as many
connections as it

Your system isn't configured for high network throughput, you
want to put something like:
kern.ipc.nmbclusters=32768
this might also help:
net.inet.tcp.tcbhashsize=32768
put those into /boot/loader.conf

I increased maxusers to 128 (2560 mbuf clusters) and it ran out of mbuf
clusters again. Then I increased it to
