How can I improve speed between buttons tap/click using Selenium Appium python

I’m learning and writing a script to test an iOS app by using a selenium python script with Appium.

But between two button taps/click some time it can be a little bit long, between each execution.

            time.sleep(0.8)#loading page

I would like to know if I can optimize this part of my code, to click/tap instantly the buttons.

Thank you
