[@harikavolam7123]

Thanks for explaining in both code and internal visualization of threads. Great explanation. You have explained complicated topic in very simple way.. Thanks a lot

[@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

[@pepperjack6749]

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

[@sharatchandra9198]
