    Memory Hit Ratio

    Need an example of computing the hit ratio for memory. Anyone know of any links?

    I'll have a guess and say that he's probably after something to do with how often a requested memory location has already been loaded into the CPU cache and thus doesn't need to be fetched versus not.

    How you calculate it is however anyone's guess. Surely it depends on what you're actually doing? If I request the same memory a million times I get 100% hits.
