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 :-). John Dyson
