I remember that presentsation, it was exciting and very cool ;-)

Hmm - integrated/used it at one time ... but ... I'm not sure of that is still true of it it even really made it out.  That was all happening when I was still hacking on Alphas (which was a long time ago).   We'd need the active NetBSD folks to chime in on curent state.

At the time (and I'm doing this by memory) the buffer cache stuff needed a rewrite which I thought FreeBSD did/was doing at the time.

In those days, FreeBSD was within epislon on of Tru64 on Alpha performance and NetBSD had a ways to go.  At the time, I gave a couple of Alphas to somebody in the UK (I've forgotten whom); who was going to redo it.

Last I knew, no.  I was under the impression, the work FreeBSD did rewriting the Mach stuff paid off for them at the time.  I have FreeBSD, OpenBSD and Linux (and Mac OSx) all running on my systems here.   But the problem is that the HW is all over the map in termns of release date, so I'm not sure which is faster at this point.   The *BSD systems are the easiest to admin and clean/simplest (which is why they only systems I have exposed is an OpenBSD box).  But they have uses ;-)

My data was from those days, and FreeBSD was winning, but thats a >>long<< time ago.  Lots of bits have been types into to the kernel of both systems, so you tell me,
