Maximum performance of CPU only

[Deouss]

Let's say I want to do some very heavy calculations as fast as possible by esp CPU. After calculations also need to perform super fast bit-banging - unfortunately there is no work around. During that time nothing can interrupt of interfere with that calculations. How to properly achieve that? What is the highest possible speed I can achieve? How to get full 240Mhz computation power of CPU ?

Excellent share especially FreeRTOS has this much needed cross platform support
