Time actions spent waiting for a remote executor, averaged over profiled builds. A rising line means the executor pool is short of capacity.

Slower targets than last period

No target's median duration rose more than 20% (3+ timed runs in both periods).

Non-hermetic actions

Same inputs as an earlier build, different outputs: timestamps, randomness or undeclared inputs. They defeat the cache every time.
