TCP_STREAM to measure how fast teh ip440 can pass data. TCP_CC to measure connection setup and teardown TCP_RR to measure request/response over a single connection TCP_CRR to measure request/response using a new connection each time. another tool that looks interesting is DBS http://shika.aist-nara.ac.jp/member/yukio-m/dbs/index.html looks like it can be used to coordinate activities of a number of comptuers involved in a single test. one piece that i will need is a machine that can saturate a 100BaseT. anyone have any suggestions? my linksys 10/100BaseT (if_ed.c) card aint gonna do it :) jmb To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
