I've been experimenting with 6.0.7 and 7.0 on my 5 Mb IIci looking for
the setup which maximizes the performance as measured by MacSpeedo 2.5.
I have a Micron Cache Card installed, and the 4 256K simms in bank A. I
am using the onboard video.

In brief, I've found that a cache setting of 384 K gives best performance.
This setting pushes my system size over the 1 mb mark so applications are
running in Bank B.  MacSpeedo numbers are; CPU 7.91 - 8.03, Math 175 - 185
and disk 2.8 (105MB quantum).

At this cache setting I obtained the same level of performance using either
6.0.7 or 7.0.  I was supprised to find that running under b/w or 256 colors
made no difference either.  Furthermore, I found that none of my INITS/CDEVS
(or EX/CP's if you prefer) made any difference either.  Neither SuperClock
or Omega-SaneFPU made any measurable difference.  The cache card improved
CPU and MATH numbers by 12 percent.  Given that it cost about 8 percent of
the CPU price, its a deal and ALL IIci users should own one.

I can't address network printing.  I haven't noticed any print slow down
on my serial ImageWriter II, but I don't print on it alot.
