This is a rather quick fix for Eventy that I have made with the v0.4.3 release. It should improve performance and technically lower the load average. This is due to the removal of the event-loop which would periodically (configurable or using yield) check if there were any enqueued events and then dispatch them. We now dispatch events on the call to push(Event). Hence no spinning loop is needed which increases the time that thread is present in the run-queue hence increasing the load-average, secondly the dispatching would technically take longer as no signalling occurred - one would just wait for the kernel to schedule the event-loop whenever it decided to (in our case of using yield()).
You can take a look at the release notes, or alternatively see the source code and DUB repository
