Best way to make autosave fast?

What’s the best way to make autosave fast?
My typical file size is around 1GB with lots of poly surfaces and some lines (plan drawing overlapped…)
I have nvme SSD(pcie4) and while it’s vastly better than HDD, still not giving satisfactory speed for me.
If I want to crank up the autosave speed as much as possible, what is the biggest limiting factor?
Would pcie5 SSD help at all? Or is it about single thread cpu speed?

That is amazing!
It takes 1/3 of time!

Is there any way of making only autosave not compressed?
