Improving Snort Performance?

Ok, I've tuned my kernel. Installed Phil Wood's MMAP'd libpcap (Hi Phil) so that I don't lose packets with bursty traffic. Tuned my ruleset, What other tricks are there for improving snort performance?
I can't remember who it was, but someone suggested the [ip/mask,ip/mask,ip/mask] notation for $HOME_NET was causing problems and it was quicker to list them and a set of rules for each one - anyone else tried this on a live sensor? - I'll try it tomorrow to see if it makes much difference - does anyone have any more ideas?
What experience have people had with barnyard yet? Does it really make that much difference in IDS mode since we're hopefully only alerting relatively infrequently in comparison with the number of packets being seen by the sensor.
What's the score on the AC_BM pattern match stuff? Do we need an FAQ section for performance (Marty???)
