I downloaded 2020b update 5 version which said to be compatible with rosetta 2. Although I downloaded the right version matlab works incredibly slow I even cannot close the app. I tried to do what this problem says but even though I disabled the MathWorks Source Control Integration it still was slow. Is it about the java heap memory and how much should I inrease that? Thanks.

Mine performs a quite faster when I work offline. if its an option for the type of your simulation, maybe go try it.

In my case, the lag disappears if I start MATLAB from Terminal everytime. It's strange to see that while it could run good, it is running slow when started from the ususal App icon.
