I've been musing recently on capacity planning for systems which see
very peaky workloads. For example, in the financial markets, a very busy
day can be much, much busier than an average day; this means you need to
plan for relatively low utilisation on the average day, in order to give

The product I work on is already shipping something which does the
equivalent of a small subset of madvise, so it would be generally useful to
us.
I have to echo the other positive comments about the lgrp tools. It's

Wow - this is a very, very general question. There are, however, a couple of
general rules which usually stand you in good stead when looking at
optimisation:
