- This is a valuable observation. With virtual-memory machines,
- it's rarely the case that stuff stops working if you don't have
- enough RAM. Usually what happens is that some things take
- longer, as they cause pages to be swapped in and out more
- frequently.
-
- You probably could do development on an 8MB (ok, 12 :-)) machine
- with BC 5.0 if all you need to use is the command-line tools.
- The 16-20 MB memory minimum is mostly the recommendation for
- people using the IDE.
-
- Just to complicate the issue:
-
- When you get below 12 MB, your choice of WinNT vs Win95 can make
- a very big difference. WinNT takes about the first 4-6 MB of
- your memory, whereas Win95 takes a more modest ~3, so I'd expect
- to see better performance from Win95 if you don't induce paging.
- When you induce paging by running a program that needs more RAM
- than you have, WinNT does _way_ better because its VM
- implementation is MUCH faster.
