Code Freezing?

[mmliam]

My application uses an ESP8266 that is normally in deep-sleep, wakes to an event, executes several 'imports', processes the event related code and goes back into deep-sleep. The processing of the event related code appears delayed, and the imports are suspect.

Given that the imports are executed at every boot-up, would I be correct in assuming that the overall process would be faster if the code were frozen?

Frozen code imports much faster (almost instantly) and does not use RAM for the code or for compilation.

Thanks robert,

I've never frozen code before. I have a couple of descriptive links; but I may be back if I have issues - lol.
