By VM you mean Virtual memory?

If so then hardware has played a role in this.  Even if Linux suffered =
from
the same fits as before the hardware has/would of come along to help it =
out.
During the 2.2 era RAM prices where high and boards that support lots of =
RAM
very costly, however today RAM is very cheap (in comparison) and boards =
that
support 4G are common.  Plus RAM has gotten faster along with the CPUs
meaning VM plays less of a role in system performance then it used to.

Be interesting to see the same test ran before done on a newer system =
just
to see how much the hardware has help vs. code changes.

But I laugh my alpha system's 2 CPUs L2 cache combined is the same as =
one of
our production 2.2 Linux systems. Amount of RAM used to be a big deal =
now
the speed of it matters way more than size funny how things change.

I think there is more to argue over which Distro to use in Linux then =
Linux
as a whole vs. FreeBSD in the way of features performance and =
functionality
in their current states.  Think of it more as a choice between salad or =
soup
on the side than beef or chicken as the main course. :)

The chain of thought I put into deciding an OS for a system is

Windows or *nix?

If *nix:

BSD or Linux?

If Linux:

RPM, deb or Scratch?

Etc, etc you get the idea, just go thru the motions comparing until one
remains.

I meant to put this in my last reply, not to start a flame war or huge
debate on the topic but ratter to show that it's more a matter of =
personal
choice on which OS you choose and why.

Like I said Salad or soup... And it seems some people are just big fans =
of
one and stick with it.  Me I like variety so I'll continue to dabble in
both.

FreeBSD used to have some real advantages over Linux, especially under =
heavy

load and the TCP/IP stack performance.  Matt Dillon did an excellent job
with=20
the FreeBSD VM.  Where Linux would often thrash under extremely high =
loads=20
and become unresponsive (to the point that you couldn't even log in),
FreeBSD=20
would just chug along slowly but surely.  However, from about 2.4.18ish =
on,=20
the Linux VM has really come into its own and works quite well.  Also, =
the=20
2.4.x, the TCP/IP stack has improved significantly over the 2.2 series =
and=20
provides some stiff competition for FreeBSD.

Since the 2.6 kernel implements Rik's rmap VM code, it really flies even
under=20
heavy loads (Rik has conversed with Matt about VM performance).   =
Several of

the distro's backported this code to the 2.4 kernel (Suse, Redhat,=20
Gentoo...), so many have already seen the benefits of it.
=20
I haven't seen any recent benchmarks, but I doubt FreeBSD has these same =

advantages over Linux that it used to have.  FreeBSD is a great OS, and =
is=20
still constantly improving just like Linux, but it doesn't have as large =
of
a=20
developer community as Linux and thus doesn't tend to progress as =
quickly.
