Casper's membuf (replacing bufmod) is one area where performance can be made much better but he's so far resisted suggestions to put it on a path into Solaris. I've also spent a weekend working on the HP-UX bpfmod and had that functioning except for one major area: delayed delivery of packets up a STREAM. I've not posted the results anywhere public because I'm not clear on the licensing. I've also raised some suggestions of being able to do things like DMA directly into memory mapped in to or from user space at the NIC level, rather than have to copy it. Crossbow also has the potential to aid in watering down the packet flow being captured if the expression to match on fits within the capabilities of the NIC's inbuilt classification capabilities.
