The Craft Scheduler still uses the primary thread for task scheduling. This results in the main thread still having to do work as part of the dispatching of async tasks. If plugins make use of lots of async tasks, such as particle emitters that want to keep the logic off the main thread, the main thread still receives quite a bit of load from processing all of these queued tasks. Additionally, resizing and managing the pending entries for all of these asynchronous tasks takes up time on the main thread too. This commit replaces the implementation of the scheduler when working with asynchronous tasks, by forwarding calls to the new scheduler. The Async Scheduler uses a single thread executor for "management" tasks. The Management Thread is responsible for all adding and dispatching of scheduled tasks. The mainThreadHeartbeat will send a heartbeat task to the management thread with the currentTick value, so that it can find which tasks to execute. Scheduling of an async tasks also dispatches a management task, ensuring that any Queue resizing operation occurs off of the main thread. The async queue uses a complete separate PriorityQueue, ensuring that resize operations are decoupled from the sync tasks queue. Additionally, an optimization was made that if a plugin schedules a single, non repeating, no delay task, that we immediately dispatch it to the executor pool instead of scheduling it. This avoids an unnecessary round trip through the queue, as well as will reduce the size growth of the queue if a plugin schedules lots of asynchronous tasks. |
