Also, for a long time, Linux had a hard time with lots or routes. No longer applies. In fact Linux is now faster than BSD up to about 60-70,000 routes. BSD is faster at about 200,000. In between its about even. Where/how are you doing simulations with that many routes?

These are just numbers reported by Alan Cox and Alexey Kuznetsov.

Feeding full routes to a linux 2.0.3x box running gated, I get: # cat /proc/net/route | wc -l 54677 and that command takes 13s to complete.

Well thats great for benchmarking procfs B)

I wonder how long 'netstat -rn' takes on *BSD with 54k routes.

% time eval 'netstat -rn | wc -l' 53606 2.6u 2.3s 0:05.74 86.4% 64+407k 0+0io 0pf+0w I don't know which process the u and s numbers refer to; it could easily be wc... This is on a box with an AMD K6/300 and 256mb ram (unneeded normally, but it was starting to swap a little at 128m. After being up a day (we upgraded hardware last night; before that it had been up a month) it looks like 144mb ram would be plenty.) It gets 4 full views and several private peers, with 4 ethernet cards and a quad (et) sync. Gated's ram is not too bad for 4 full views: root 182 0.0 15.6 40088 40440 ?? S 11:58PM 2:22.73 /usr/local/sbin/gated We normally push 10-12mbits/sec but only around 1k packets/sec. With about 50 (ipfw) filter rules, the cpu is normally around 5-15%, almost all "interrupt", as might be expected. -- Pete
