how or where async function in a web api controller can help me?

Question

hi,

I just made one web API with core 9 with entity framework and all actions, i found that all the methods are made with a sync.

q1) so my question is where or how it can help me , because in my case i call my controllers action methods from java script in JavaScript i can can it in async or synchronous way, question came to my mind do i need async in the action methods of controller.

q2) and if i am not beneficial in above case then where i would be?

yours sincerely

Use async in Web API when performing I/O operations. it improves performance, scalability, and responsiveness under load. Q-1 Ans: if your controller interacts with databases (like EF Core), external APIs, or file systems. Even though JavaScript can call your API asynchronously, using async on the server frees up threads during I/O operations, allowing more requests to be handled efficiently. Q-2 Ans: High-traffic Web APIs: Handles more users without blocking threads. Long-running I/O tasks: like DB queries, API calls, or file access — improves responsiveness. Cloud/hosted apps (e.g., Azure App Service): Scales better under load with fewer resources. Apps with many concurrent operations: async prevents thread pool exhaustion and improves performance. Good Luck!
