Hi all,

just a thought here:

Of course the benchmark setup and procedure is strange but..

it could be improved, I think.

Have a good collection of tuning parameters for "popular cases",
advertised properly so it gets hard "to miss them".

I am a sysadmin and, over the years, I had to run file servers,
database servers, web servers, tomcats...

Well, most of the time I set it up and "it just works" because the
system in question is not maxed out, not even close to it.

But if I want to squeeze the last 20% out of it googling starts, and
here and there I find hints how to tune the OS, the file system, what
scheduler to use etc.

It would be great to have a set of case studies at hand, e.g. under
the /usr/share/examples directory, that describes tweaks to have a
performing postgresql server, or mysql, or apache or a desktop or..

Things I find, for example, in the BSD Magazine.

Maybe benchmarks become more meaningful then..

A general remark for people doing benchmarks for comparison: you need
a well-informed system engineer for the systems you compare. So, if
you compare a Linux system with  FreeBSD, have two experienced admins
that know their OS well.

Peter
