I think one of the reason PC-Minix bogs down is the buffer cache is only
40K.  This is a guess -- not a hard fact.

An attempt was made to alleviate the problem with a ram disk,  but that's
not the Unix way of doing things -- a larger buffer cache would be nice
(i.e one which can hold all the passes of the C compiler, the libraries and
the editor and shell -- about 200k would be nice).

Then you get into these nasty 8086 segmentation problems.

I don't think swapping  is the answer -- I tend to agree with ast (make the
OS big enough and swapping becomes a self fulfilling prophecy).

A system that can use more RAM for processes and buffer cache would be
nice.

(I thought CS professors like to assign tasks like "write a swapper" to go
with things like "write a drum driver").
