WARNING: this RT is long! and very dense, so I suggest you to turn on your printer.
Which of the following does your RT address:
- Deciding when the overhead of caching is worthwhile on a given item.
(and which part of the overhead - the act of storing, or the resource use)
- Deciding when to purge the cache (aka, a better StoreJanitor/MRU)
In the first scenario I'd have trouble seeing how this calculation could be any less costly than the current. But only testing would tell for sure, and I'll be very interested to see it develop.
It isn't about being less costly to come to the decision, it is about making
better decisions. Consider it a more advanced branch detector.
Right on!
