Speed up a python script

I run a s that scans part of my screen and when it finds the image i'm looking for it strikes down a key .

The problem is that it's so slooooow and i want it to run 5x faster at the very least

I use the pyautogui

Here is what my script looks like :

while 1:

if pyautogui.locateOnScreen('Transaction success.png',region=(5,5,60,60), grayscale=True, confidence=0.70) != None:

    pyautogui.press('n')

    print("transaction succesful ...")

else:
    print("Scanning...")

please help if you can
