I am *brutal* to FreeBSD, but it is getting difficult to find places where it can easily be improved (some of the performance "nits" are due to differences in philosophy and not actual performance problems.) With the latest pipe improvements, I am running out of steam. Indeed, my goal is to "find" performance problems. If anyone has a "cache" of programs to show performance bottlenecks, please email them to me. They will be used to improve FreeBSD's performance, and if I don't do it, DG, BDE or someone else will work on the code. There is another layer of improvements that I have been thinking about, but those require more involved work, and I want to work on easier stuff right now :-). Brain vacation time :-). I would suggest taking a look into uptime benchmark. Make FreeBSD with 50-100 simultaneous users, WWW server, news server, ftp server and lots of nfs in the same machine to stay up for at least weeks in row, instead of days. Popularity of the results is guaranteed, and that is the benchmark professionals value the most. -- Heikki Suonsivu, T{ysikuu 10 C 83/02210 Espoo/FINLAND, hsu@clinet.fi work +358-0-4375209 fax -4555276 home -8031121
