Thanks!
Raylib's performance is excellent. I used love2d before but I wasn´t happy with the performance so I tested a lot of frameworks/engines and raylib was by far the best. (I was only interested in drawing shapes on the fly, so if you want to use textures/sprites there might be better options out there)
It is not perfect and has some issues but the performance is really awesome. The compile times are also fast (but I can only speak for small to medium-sized projects). I use Raylib_CsLo c# bindings and Visual Studio, so if you plan on using it with c or c++ the performance will probably be even better.
I hope this helps :)
