ESP32 4x SLOWER than ESP8266

[PeteKnight]

It’s difficult to know, from what you’ve written, how much investigative work you’ve done yourself to try to narrow down the cause of the issue.

Personally, I think I’d try some of these things:

1. Using different versions of the ESP32 core. If you’re running the latest version then try downgrading.
2. Try other types of ESP32 dev boards from different suppliers
3. Try Non SSL versions of the Blynk libraries.
4. Check that there’s nothing ESP32 specific that can be switched off in your code to give more speed (turning BLE off for example).
5. Look at forcing the ESP32 to use its multiple cores differently.
6. Research if others are reporting issues in certain situations, to see if this a Blynk library issue of something else.

I’ve put the tutorial text into the block below to get proportional text. Let me know if there are any questions, comments or suggestions on improvement. Please also share your experience if you are using any of these techniques yourself! This Tutorial will demonstrate some useful implimentations of FreeRTOS on the ESP32.

Might be useful when looking at how best to use the multiple cores.
I’ve seen another thread (but I can’t be bothered to search for it) where a community member ran Blynk code on one core and horrible code with blocking delays on another core, just to prove that it can be done without affecting Blynk’s operation.
