With a Debian Linux (2.4.xxx kernel) it handled about 60 thousand packets per second. This with several rulesets: * keeping track of usage statistics for some 2000 hosts on the network * just counting all traffic that went past * classifying all traffic into 4 different destinations At the same time it was running a MySql database for storing results and an Apache web server (for viewing the results). If the only ruleset was just counting all traffic and without the database or web server running, it could do (IIRC) over 90 thousand packets per second.
