Been building a task-dispatch API for a couple months, and the thing that bit me wasn't the async part — it was duplicate work. Two agents an hour apart paying twice for the exact same normalized input. Memory gap, not sync gap. Once I hashed canonical input JSON, cache hit rate on real traffic was higher than expected — mid-teens % once a handful of workers were live. Curious if anyone here's tried cross-agent result sharing without bolting on a full pub/sub layer.
