In the right situations, the use of multi-threads can allow for application speedup. Provide a small code example that illustrates how threads can be used to arrive at an appropriate result. Identify if there is a point where too many threads might impact performance of the application. g

Explanation:

Threads allow an applications to run faster because they allow various tasks to run at the same time instead of doing one at a time and having to wait for one to finish before starting the next task. However, if too many threads are running at the same time, or a thread has a very large task or requires another task to finish before finishing its own then this can drastically impact performance. Mainly because too many resources are being used at a single moment. The following code is a small example of how threads work in Python.

import threading

import time

def thread_function(name):

   print("Thread {name}: starting")

   time.sleep(2)

   print("Thread {name}: finishing")

thread1 = threading.Thread(target=thread_function, args=(1,))

thread1.start()

time.sleep(1)

thread2 = threading.Thread(target=thread_function, args=(2,))

thread2.start()

thread2.join()
