dev.cache-hit-efficiency Calculator
Calculates cache effectiveness from hit rate, read-through latency, cache capacity, and eviction rate. A cache with 95% hit rate eliminates 95% of origin reads — the remaining 5% are cache misses that hit the origin at full latency.
Inputs
Total Requests
Reference formula or conversion factor shown for context.
Cache Hits
Reference formula or conversion factor shown for context.
Cache Miss Ms
Reference formula or conversion factor shown for context.
Cache Hit Ms
Reference formula or conversion factor shown for context.
Results
cache hit rate
Fraction of requests served from cache without hitting the origin. Above 80-90% is generally good; below 50% means the cache is not effective.
avg latency with cache (ms)
Time from request initiation to response received. Composed of processing time, network round-trip, and queuing delay.
avg latency without cache (ms)
Time from request initiation to response received. Composed of processing time, network round-trip, and queuing delay.
latency reduction
Time from request initiation to response received. Composed of processing time, network round-trip, and queuing delay.
misses
Reference formula or conversion factor shown for context.
