What are the system requirements for a Mac Book Pro suitable for working with Figma with a very structured Design System?

Hi everyone, what are the system requirements for a Mac Book Pro suitable for working with Figma with a very structured Design System that uses modes, text variables, light/dark mode, device variables etc?
I have a
Mac Book Pro 2.3 GHz Intel Core i9 8 core
2.3 GHz Intel Core i9 8 core
Intel UHD Graphics 630 1536 MB
16 GB 2400 MHz DDR4 memory
Sonoma 14.5

On some files in which I have been using the Design Sytem for a few weeks I have noticed a crazy slowdown which hinders my work a lot, the memory use used by one of the files in which I have slowdown is only 5%

So I don’t know if it’s a Figma problem or if I should consider changing the computer.

Thanks in advance

Anything M series would beat it to the dust. Even M Air would fly, any modern M2 or M3 would be a great choice.
