Matlab 2021a runs extremely slow on macOS Big Sur version 11.31
1 view (last 30 days)
My Matlab(2021a) code is running very fast on windows 10 Pro desktop (Intel i7 CPU @ 3.20 GHz, 48 GB RAM), but it's extremely slow on macOS Big Sur (M1 chip, 16 GB RAM). I find the data reading inside the loops is significanly slower on mac. Is it due to some optimization issue? What is the possible solution to make matlab faster on mac?

There was a performance regression in the later versions of Big Sur, and this issue is being investigated currently.
In the meantime, the workaround is to start MATLAB from the Terminal as described here. There are no additional startup flags needed.
