Looks like I picked the wrong kernel. :( Is there a kernel that is
regarded as the "best" performer for processing like gimp, spreadsheets
etc ("scientific workstation" or "graphic workstation" might be the
categories?) Or is just switching off low-latency and pre-empt with
gentoo sources likely to be fastest? Pity that desktop responsiveness
etc is so hard to measure, that we didnt look at that.
The gentoo kernel document mislead me a bit here. It might need a bit
of a review to make the distinction that gentoo-sources is for
interactive desktop usage, at a significant penalty to performance -
performance has a particular meaning here.
The comparison was meant to be as standard an install as practical, but
that soon became impossible due to debian stables old packages etc,
whilst gentoo-sources is the reccomended kernel for gentoo, it seems to
have exacted a penalty.
There is also spiders comment on -O2 opts and celerons which will need
confirming on this hardware at some time. What does Mandrake do here?
Unfortunately, we are out of time, so the ideas here will have to wait
...
Gotta look at this some more ...
