- The TOS MMU table is very simple and only a few of the entries should ever
- be used. Once they have been, they'll stay in the buffers in the '030 and
- should not affect speed.
-
- It should be possible to make the Falcon work with the MMU turned off, if
- you instead set up the transparent translation registers to disable caching
- of the hardware registers.
- I'd be very surprised if it made anything faster, though.
-
- MiNT without memory protection shouldn't touch the PMMU at all, by the way.

-
- Are your caches turned off by default?
-
- Someone once mentioned that you could speed up memory moves if you changed
- the default cache settings. At the time I thought that sounded reasonable,
- since I assumed the '030 always loaded complete cache lines. Apparently
- it doesn't do that, however, unless you have burst mode memory. I guess
- changing the 'allocate on write' bit might be useful to keep written data
- out of the cache, though.
