Increase default optimization level from -O1 to something more optimized

[zamazan4ik]

Hi!

I found that in the current Makefile default optimization level is -O1. I see that before 2538c3a it was -O2 but suddenly was changed to -g and then -O1.

Could you please elaborate on the reason for decreasing the default opt level? Probably it was just a mistake and we can revert to -O2 (or even -O3) once again.

Thanks!

P.S. By the way, did you consider enabling Link-Time Optimization (LTO) for the project with -flto flag? It can help with the binary size reduction and allow the compiler perform more optimizations "automatically".

Thank you for the suggestions!

I had -O1 early on because I was getting weird behavior with -O2. This was very early in the project, and it's possible it can be elevated now.

I haven't considered LTO maybe that's a possibility.

Could you please try to enable -O2 -flto to the project? If it works fine - it will be great since by default users will get a more optimized version of your awesome project!

Thank you, yes if I test and there are no issues, I'll add it.

This is in, on main branch. File size went from ~850KB to ~600KB.
