- I think your first approach seems reasonable. However,
- you don’t explain why getting called 4-5 times a second
- is inadequate; is it too long a delay between responses?
-
- If you examine Print Monitor, it takes large amounts of time
- at irregular intervals, rather than small amounts of time
- very frequently. I would also note that a 68000 and probably
- a 68020 without the 851 cannot do a context swap very
- quickly, thus encouraging fewer, longer time slicing.
-
- I would note that drivers and DA’s can get more frequent
- time slices, and it might be worthwhile to try installing
- a driver with dNeedTime and see what happens. If things are
- busy, there’s no guarantee you’ll be called often enough.
-
- As for intra-application communication, Apple announced at
- its conference for developers last April that it is working
- on such capabilities, and that such would be included in
- System 7.0. I don’t think there’s been much public comment
- since then, although the best guess on 7.0 I’ve heard is
- 2nd Quarter 1989.
