- If you're running under Win95, keep in mind that Win95 is going to
- need a lot of memory for itself. When you tell Executor to use more
- memory than is physically available, it needs to use virtual memory
- and that slows it down.
-
- "executor -info" will tell you how much free memory Executor detects
- and how much it decides to use. In general, Executor tries to choose
- a sensible default memory setting. However, tweaking the defaults can
- certainly help (especially if you have a lot of memory).

-
- It depends on what you are doing. Even a blazing processor will be
- brought to its knees if it's paging to disk all the time. OTOH, if
- Executor can fit in RAM then you want as fast a processor as possible.
-
- Larry> Is E/D's code optimized for the pentium chip?
-
- There are a few pieces of Executor here and there (mostly in the
- graphics code) that are optimized for the Pentium. Overall, though,
- it's not, because gcc (the C compiler we're using) doesn't know how to
- optimize for the Pentium. [Intel's version of gcc that can optimize
- for the Pentium has some nasty bugs].
-
- The key CPU feature that Executor takes advantage of is the "bswap"
- instruction which was introduced in the 80486 (and of course exists in
- the later processors). Executor doesn't use any Pentium-specific
- features (although we may use Intel's MMX multimedia extensions in the
- Q4 '96 Pentiums eventually).
