Thundering herd problem in shared timers

Open Thomasdezeeuw opened this issue 3 years ago • 3 comments

Pr #376 (knowingly) introduced the "Thundering herd problem" for the shared timers. If multiple worker threads have the same timeout (based on the shared timers) and all attempt to schedule the same thread-safe actor because of it will pointlessly waste resources, as the actor can only be scheduled once.

This should be resolved when fixing #284.
