I offered on the freebsd mailingliste a few benchmark results under
compareable machines.

SS2, 486/33 Linux Slackware, 486/33 FreeBSD 1.1, 486/33 FreeBSD 2.0 ALPHA

It would be a good idea to do that again with

	FreeBSD 2,0 RELEASE
	Linux XXXware (with XXX= Slack or LST)

		the scsi cluster code).

: I have a 386sx/25 with 4Mb, with a 200+ MB IDE, Hercules card ...
: It is used right now for loading (and reloading) FreeBSD to get some
: notes down on the installation procedure.

Not just the leading edge ;-) But should show performance differences
in a minimum environment.

What strikes me most are the 4 MB RAM. With that equipement I normally
wouldn't do a benchmark, since you aren't sure if swapping or paging
(depends on the amount of daemon programs that are executed when going
into multiuser mode) give strabge results ...

You wouldn't expect a benchmark of a SPARCstation with 4 or 8 MB in a
Unix Magazine, too ;-)

Slackware 2.0 is surely a good staeting point. I'd strongly suggest
to do all the benchmarks in single user mode....

: I was going to look at I/O (iozone), the Byte Unix Benchmarks, and compile

What about SSBA and bonnie ? Don't forget to use bonnie, too, as a disk 
benchmark running on a 50 MB file. It shows read write performance doing
i/o blocked and char. Then Rewrite and Seek time. Really interesting
values.
