Yes, of course normally. Do you use a proper thread pool?
Would you like to show any code example from your approach?
Can you reuse a higher level programming library?

It depends on the number of processors and the amount of input/output operations with
devices.
Did you read about such technical details and other design factors in previous
discussions?

Would you like to apply non-blocking algorithms?
