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
