Busy Frontend
Performing asynchronous work on a large number of background threads can starve other concurrent foreground tasks of resources, decreasing response times to unacceptable levels.
Resource-intensive tasks can increase the response times for user requests and cause high latency. One way to improve response times is to offload a resource-intensive task to a separate thread. This approach lets the application stay responsive while processing happens in the background. However, tasks that run on a background thread still consume resources. If there are too many of them, they can starve the threads that are handling requests.
This problem typically occurs when an application is developed as monolithic piece of code, with all of the business logic combined into a single tier shared with the presentation layer.
