Bitcoin core synchronization too slow, only 16 hours of blockchain in 20 minutes

I have Bitcoin Core stored on my external disk and currently I am on 39%. but the problem is that it is getting slow for some reason. The Bitcoin Core Qt app is constantly beachballing on my Macbook Air M1 for some reason. When I click on something the response will appear after 5 seconds or so, it’s terrible.

Is this normal, or it will get worse?

Right now, I am on Dec 10, 16:23:29 2017 and it took 20 minutes to get there from Dec 10 00:20:02 2017.

Is this normal? Should I expect even bigger slowdown after 50 or 60% mark?

Any advice how to speed things up on my Macbook Air M1? I got to this 39% after running it for like 4 days – sometimes I turned it off for a couple of hours though.
