What is the expected behavior?

https://docs.espressif.com/projects/esp-techpedia/en/latest/esp-friends/advanced-development/performance/reduce-boot-time.html says after optimizing the startup will be around 27ms.

What is the actual behavior?

In my tests it's at the minimum of 56ms.

Steps to reproduce.

Make optimizations of https://docs.espressif.com/projects/esp-techpedia/en/latest/esp-friends/advanced-development/performance/reduce-boot-time.html and check when a pin goes high.

I tried it with 5.2.3 and 5.3.1. There is practically no difference. Here is a picture of my logic analyzer:

Hi @weoiss1998

May I know if you have done every optimization? Especially Disable Boot ROM Log Printing. Need to burn refuses :

Hi @zztiger123 ,

yeah i did this aswell.

I have discovered that it is an ESP32 S3 WROOM 2, is this perhaps the reason?
