There are three drawbacks:
- the MP2000 has very little RAM. Sean was complaining that a very
early version of ATA Support slowed down his MP2000. This old build
was copying itself entirely in memory and I think Sean had the debug
build or something like this. Now, I only copy the smallest part of
the code as possible.
The system uses this RAM for all graphports, and the MP2000 having 16
grays, it means 8 times what it takes on a MP130 plus the size
difference.
- This RAM (hence the slow down experienced by Sean) is used to
decompress and cache packages (aka virtual memory). Taking too much
memory will slow down the Newton.
- This heap isn't garbage collected. Any leak there is definitive.
