I don't really want to sound cynical ;)
But; how much memory do you have? Your kernel is about 2Mb smaller=20
than the one I'm using but the difference represents about 0.4% of my tot=
al
memory which I suspect is almost always incompletely used.

Could I ever see eany effective difference with an "optimised kernel"?

And of course if I ever add anything I'd have to remember to take the=20
time to recompile -- and as I get older remembering is not so easy!
