Fast compiles using ESP32 and Arduino IDE 2.3

[frankcohen]

I'm using Arduino IDE 2.3 on a MacBook Pro laptop 2.3 Ghz Quad Core Intel I7 on Sonoma 14.4.1. My Reflections project has 1 .ino file and 25 .cpp files. It's about 15,000 lines of code in total. Code is here: https://github.com/frankcohen/ReflectionsOS. It takes about 8 minutes to compile the code. During the compile the aggregate CPU is 11% used. It seems the compiler is using 1 of the cores only. What ways are there to compile the code in less than minute? -Frank
