- There's a small point that is sometimes overlooked when it comes to what
- a cache really does - how much it helps can directly depend on the program
- that is running. For example, in the rare case that there may be a 128k
- loop in a program you use often, a 128k cache will make a BIG difference
- for you - since a 64k cache could re-load itself twice a loop [depending on
- how it was designed].
-
- Here's my advice : try to find people who use the programs you use and find
- out if their caches help out a lot or don't. If whatever magazine gives
- statistics for various programs and you use one of them - utilize that
- magazine. Generalized comments about caches are usually pretty accurate but
- not always.
