Hi Perry,
I thought about doing this but wanted the solution to scale in case the
files were really huge or there was an overwhelming number of them. I've
noticed that this is a great approach when you need things to happen
immediately when they are called, however, the timing in this application
is loose so, I'd rather buy the time I need to load the files from the disk
on demand than be limited by the size of the cache.
I'm assuming that this "cache" is in memory... what are the effective
limitations here? Assuming a 64bit OS for now, are we basically just
limited by the availability of RAM on the system? Or is are there limits
set in the Chuck executable?
Best,
Mike
