Make SubprocessEnvManager take asynchronous steps (#2265)
SubprocessEnvManager takes steps synchronously to reproduce old behavior, meaning all parallel environments will need to wait for the slowest environment to take a step. If some steps take much longer than others, this can lead to a substantial overall slowdown in practice. We've seen extreme cases where we see almost a 2x speedup from using asynchronous stepping, with no downside for our faster environments. (Bouncer 16% improvement, Walker 14% improvement in tests). This PR changes the SubprocessEnvManager to use async stepping. This means on the "step" call the environment manager will enqueue step requests to workers, and then only wait until at least one step has been completed before returning. |
