如何计算Cache Size
learn.whatIsHeading
A cache size calculator determines the optimal cache memory allocation based on working set size, hit rate targets, and available memory. A 90% cache hit rate typically requires caching the most-accessed 10–20% of data; adding more cache beyond that yields diminishing returns.
