Ok, it's probably a stupid question, but given the relative ease of putting 4gb+ ram on a 64bit platform, could packet per second performance be improved by brute forcing the route lookup as an array of 1 byte destination interface indexes for a contiguous swath of /32's from bottom to top? Route updates would be a little ugly, 2^24 bytes to rewrite for a /8, but forwarding lookups out to be a single indexed read ?

It turns out their throughput was singlesource/singledest, and/or large packets (so high throughput, but low pps.)I assume though that all of this is on x86 platform hardware. How does this compare to Linux or FreeBSD running on something else like the Cavium Octeon and other 64bit MIPS based processors?You'll have to ask the people playing with it on that. Me, I've been looking for some multicore MIPS + fruit for some Squid related hackery but I've been busy with other things (like, you know, making Squid-2 be able to be run on multi-core hardware in the first place..) so it'll have to wait.. :) Adrian
