MacOS save takes longer

Hi Logik people.

Recently I started moving my workstation from Linux to MacOS.
I tried iMac, iMacPro, MacPro, MacStudio.

Almost all things were smoothly migrated as they had been in Linux.
But several things bothered me.

One of them is that saving a project takes far longer than expected.
As the project gets bigger, autosave kill my time so much.

Like for a 30sec ad project, it took 1min.

Would you tell me any solution or is there anyone who have experienced the similar problem?

Thanks.

That would help me save some time.

Do you know why it only happens on macOS despite it took a couple seconds on Linux like z840.

Memory is not enough?
What do I have to take care, not only to manage the number of open libraries and batch groups?
