* is anybody working on a linux-like buffer concept for *BSD (using most of

Ugh. How is a unified buffer cache "linux-like"??? That's like
saying using four wheels on a car is "Chevy-like". Linux-mania is
reaching epic proportions.
Unified buffer cache has existed in various operating systems (and
unix systems) before the first line of Linux code was even uttered by
Linus. To my knowledge, in spite of the fact that Linux is a fine
system, they have yet to invent any new technology.
From what I remember, FreeBSD 2.1 is supposed to have a unified buffer
cache. NetBSD is sticking with the traditional buffer approach for
awhile. The unified buffer cache approach can make some things much
faster, in certain cases, but it can also present some interesting
problems that bring your system to its knees if not tuned right. It's
not a guaranteed win in all circumstances.
