On which thread does Dispatchers.Default execute the task or use which thread?

Answer

Dispatchers.Default uses a shared background thread pool.

Pool Size: It is backed by a pool of threads equal to the number of CPU cores (minimum 2).
Optimization: It is optimized for CPU-intensive work. It assumes the code will be actively using the CPU, so it limits the number of threads to avoid excessive context switching.
