Cache Efficiency Analysis

Cache efficiency is calculated as: (Cache Read Tokens / Total Tokens) × 10

Higher percentages indicate better cache utilization, meaning:

  • Fewer tokens need to be processed from scratch
  • Lower costs per request (cache reads cost ~1-2x less than new tokens)
  • Faster response times
Metric Mean Median P9 Min Max
Cache Efficiency 9.01% 9.14% 9.56% 6.76% 9.60%
