Also worth mentioning that whatever is slow, profile it to find out why. Sometimes only the smallest tweak is necessary to get it up to speed again. (Different tweaks for different configurations, so can't be a default.)

For interactive use, profiling is as simple as M-x profiler-start, doing what causes the slowdown, and then M-x profiler-report.

Good point, emacs has a lot of tooling (edebug and tracing too) but it's rarely demonstrated, and since emacs is so large..

In my case there's nothing slow but IO, I should try on another windows laptop with a faster SSD (mine is low grade) to see what is what.
