[@mostinho7]

Done thanks Thread pool instead of creating a 1000 threads which is expensive, can make a fixed size pool and submit 1000 tasks to it. 3:40 how it works internally 5:30 ideal pool size for cpu task is number of cores 9:30 thread pool size for io intensive tasks

[@vijaynandwana4289]

You are awesome, thank you for posting these videos.

[@AyushSharma-ux4fk]

A very intelligent statement. If your tasks are I/O intensive e.g. DB calls, Network calls. Most of the threads would be in waiting state (waiting for DB response or Network call response) in such a scenario having a large thread pool is the right way to go. That way you would be able to start more tasks. Thanks

[@manishghoshi3861]

The best till now. Thanks.
