Parallel compilation?

[nkolban]

Would it be possible to perform parallel compilation through threading or processes?

In an ESP-IDF environment, I commonly run "make -j5" to execute parallel makes and have so far not run into any issues. I have found that the time to complete a compilation dramatically decreases as I consume more of my CPU resources.

Would it be possible to achieve this capability within the Arduino IDE / ESP32 environment?

The arduino guys are working on it here: arduino/arduino-builder#250, but you can test it now getting the files compiled by arduino bot and replacing in your installation =)
