This PR addresses the issue explained in #289 by limiting the number of threads in the managed thread pool by
anyio
.Relate to the discussion in #tiangolo/fastapi/4221 and an additional click option is added to specify the number of threads. This PR should serve as an extension to the current implementation and if no thread limit is specified the server should work as previously and thus be able to reproduce #289.
However, if a thread limit is specified the response time will increase proportionally to the number of simultaneous requests, thus avoiding spawning threads until memory is filled.
