• Kit includes 186 unit tests, 43 security tests, and Playwright smoke tests

Why My Prefix Cache Missed Identical Requests

I enabled prefix caching in mini-vllm-rs , my Rust LLM inference engine for macOS, and submitted two identical requests concurrently to a cold cache. Neither reused a single token.

• Prefix cache missed identical requests due to delayed page visibility
• Incremental publication improved first token time by 48-93%
• Early-release policy reduced TTFT by 56.9% for 2 concurrent requests
