I've been playing Minecraft today, and all of the sudden, I am experiencing unreasonably higher ms ticks in the world.
This has happened before during the 1.14 snapshots (see MC-138550) (but far worse), but it seems to make a comeback, unfortunately.
The Problems That Occur:
Breaking a block in Survival will reappear for a few seconds before dropping
Entities are much slower than usual, especially while attacking
Eating will take a long time before it registers
What I Tried To Do:
Lower Render Distance
Lower Mipmap Levels
Lower Entity Distance
Decreased Particles
Checked Random Tick Speed
What Ended Up Happening:
❌ - ms ticks remain between 50-150, where it should be way less...
Other Notes:
:info: Random Tick Speed is set to 3
:info: Seed: 732795237935697572
In the log, this seems to come up often:
[11:43:03] [Server thread/WARN]: Can't keep up! Is the server overloaded? Running [x]ms or [y] ticks behind
I have attached the world download for those who want to confirm. Please refer to the Environment tab of this issue to get the specs. If you have an old MacBook Air lying around, use it to test the issue.

Also in what version has this world been created? It doesn't look like it has originally been created in 1.16.
A guy was running 1.16.1 on macOS 11 (Big Sur) beta, and he was experiencing the same issue with high ms ticks. But I don't know what settings he has enabled...
I don't think we can do much here as no one can reproduce this issue here with your world. Also it should be noted that your cpu is below minimum requirements.
In the video the guy clearly stated that he had no issues with this before with Catalina. For him apparently it's the OS version. No idea how this video should relate to your issue.
What is the gamerule "randomTicktime" set to?
