LLM latency SLOs mask user pain points; track p99 and sessions

A developer shared insights into the shortcomings of relying solely on p50 latency Service Level Objectives (SLOs) for LLM applications. The author explains that while p50 (median) latency might appear acceptable, it masks significant performance issues for a portion of users, leading to increased churn. The article advocates for tracking higher percentiles like p95 and p99, analyzing latency per route, and monitoring session-level performance rather than just individual requests to accurately capture the user experience.
