I routinely (each time I install a new system) increase the number of
open files & windows on my machine (MacII w/8Mb, 2 monitors) to about
30 each.  Of course this (and my dozen or so inits) requires more
system heap, so I bump that also until I get about 30% free in a
quiescent system.  I've never bothered to figure out the actual heap
impact of all of this, but this technique seems to work without
problems.

I use FEDIT+ to adjust this stuff in my boot block, but I sure would
like a better way to do it.  In particular, the system heap adjustment
is a guess and reboot until it comes close to being right, since the
OS seems to readjust to more available space.  I've tried the
HeapFixer (correct name?) program available in the archives, but it
doesn't seem to work very well for some reason.

Seems like this is a ripe area for a utility and some guidance from
Apple.  Any comments from DTS?
