Debugging and Performance Tuning in a Coroutine World
summary
Practical checklist for coroutine bugs and slow paths: shows specific use of kotlinx-coroutines-debug and BlockHound, logs enriched with coroutine context and session IDs, and a pattern for attaching action names to every suspend function. Reproduces two real failures with unit tests and debugger traces (missing language default and not awaiting child coroutines), uses IntelliJ profiler to find a costly tax multiplier function, measures coroutine counts, channel sizes, and blocking calls.
