With my testing last night, 350 clients each writing used ~700M of cache (with was the data being writen) and only ~100M of active memory. There was only a nominal amount swapped (probably getty and friends), so the number of shared pages is actually quite high with ~2.1M of resident mem showing for each process. If it were otherwise I would have quickly burned the 1G in the test server. The only thing I managed to exhaust was mbuf clusters, and that was on the clients first and finally on the server after a bit. Thanks to everybody for their input and suggestions, and I'll let you know how it works in the "wild" :). -- Chad David davidc@acns.ab.ca www.FreeBSD.org davidc@freebsd.org ACNS Inc.
