How to make Holed Design Wall

Hi everyone, I need help to make a wall that looks like this

So far, what i’ve been doing is making a multiple loops, choose the faces where the holes will be, and extrude (the wall will have some thickness) + delete the face to complete the holes. But doing so for a bigger and wider walls seems really time consuming, and I intend to make a round holes not square. Anyone can tell a better way to do this?
Thanks in advance
