Answer 1

Thread:

1. Creating a Thread is far slower than using Thread-pool.
2. You can change the priority of a thread.
3. The max number of threads in a process related to resources.
4. Thread is at the OS level and controlled by OS.
5. Using Thread is a better option when the task is relatively long-running

Thread-Pool:

1. Running a Thread on thread-pool is far faster than directly creating a Thread.
2. You can not change the priority of a thread run based on Thread-pool.
3. There is only one Thread-pool per process.
4. The Thread-pool is managed by CLR.
5. The Thread-pool is useful for short-lived operation.
6. The numbers of Threads in Thread-pool is related to the application load.
7. TPL tasks run based on Thread-pool
