Quick Decision

Use MoE communication overlap when:

• EP > 1
• token dispatch or combine time is visible in the profile
• the run is already correct and you are now tuning throughput

Avoid turning it on as an early bring-up step. It is easier to validate after the dispatcher, routing mode, and recompute plan are already stable.
