Ours is a huge project. I need to call certain functions in my code asynchronously to avoid some circular function calls. Upon receiving a specific input, I can call my function asynchronously either by using Event or Timer.
Which way is preferable considering Performance ?
Sending events to Event manager and handling them with an Event handler ? Or
Starting a timer and provide timeout handler ?
For pure performance, event-driven model will be better. Use timers only if you cannot rely on one or more of your events to get set in a timely way by the worker code, and so need a backup means by which to continue processing. This may be the case if your worker code makes external calls to a database or other remote service whose reliability or performance is unproven.
