2.9MB is way too few.  Your 4MB program will page to disk like heck
  and will run very slowly indeed.

Why do you need these parameters on the EMM command line?  If this is
DOS 6 or later, you don't need the 8128, and I would also try without
frame=NONE.

This is okay.

This is NOT okay!  You are creating a 16MB disk cache on a 24MB
machine, so you only leave yourself 4MB (since another 4MB went to a
RAM disk).  Make the cache be 4-6MB, and you will have tremendous
performance boost.

Note that the FAQ doesn't recommend to set aside more than 8MB for the
cache, even if you have plenty of RAM (which 24MB is not).  the rule
of thumb is to leave at least 8MB free after installing the disk cache
and the RAM disk.  16MB free is even better, especially if you need to
run large programs like RHIDE.
