Tracing a Slow Request Through Your Django App
Slow endpoints are difficult to detect because they don’t fail. They simply get slower and slower. Average latency may look fine, but that can be misleading. That’s why we need to look at other values, like p90 and p95, which often reflect what’s really going on. For example, p90 represents the slowest 10% of requests, and p95 represents the slowest 5%. When these values increase, users start experiencing delays.
