- Now that I've got my self a CD-ROM drive, it's pretty obvious that the current
- RamFAST driver isn't doing a great job at directory caching.
-
- It really shows with the CD-ROM drive. I mean, since the drive's access time
- is slow, I can tell that lot of the time is spent on reading the directory.
- After the directory is read, it looses it pretty fast... if I close like 2 or
- 3 folders, and then try to go back, it would be re-reading it.
-
- Questions...
-
- 1. How smart is the GS/OS cache?? Does it know when to flush the cache if the
- directory information has been changed?
-
- 2. What does it cache anyway? Does it cache both the data and the directory
- tree or just the directory tree?
-
- 3. This sort of relates to question #2, how big should the cache be set? I
- mean, if it just caches the directory, I think 64k or 128k should be enough.
- But if it caches data as well, then maybe more like 768k or 1024k... I set my
- to 768k right now. Is it too big?? I guess it really doesn't matter, because
- I'm using RF.
-
- 3. Do all 16 bit programs benefit from GS/OS cache? Do certain toolsets have
- to be started by the application?
-
- 4. Does the Apple II High-Speed SCSI card support GS/OS cache?
-
- I am going to bug Drew to support GS/OS cache :)
