Every task completion called _try_claim_and_remove_self, which acquires _scaling_mutex and _threads_mutex even when _remove_count is zero (the steady-state common case). Short tasks paid full mutex overhead per completion. Add a relaxed _remove_count.load before the locks; if it reads zero, skip the claim entirely. A stale zero just defers the claim to a later completion on any worker, matching the existing design where the claim is a cooperative race. |
