Result: 3 acceptance workers doesn't pay off on x64. Closing; acceptance stays at 2 in #129338. All runs at 10 shards, green, fitted per shard and per runner CPU type (residual noise ~5% per shard):
The 3rd worker barely moves test time (the runner is already CPU-bound with Chrome) and costs an extra per-worker Snuba bootstrap in setup. |
