Hi all

I have an application running on the v1.20.0 (official .bin release - not compiled by myself) in my ESP32-S3 (16MB Flash 2MB RAM). So I just flashed it with the new v1.21.0 (official .bin release) and I clearly noted that everything is slowest.

1. How I note that everything is slowest? My application has tasks (asyncio), where some that are network communications (TCP), UART (485), write files, display, etc. I have also one thread. So, I noted that everything is slowest, I mean, network answer is slowest, thread is slowest, and write file is slowest, etc.
2. I really don't know exactly what part goes slow and I didn't yet a specific test to find out where is slow.
3. I see that this version (v1.21.0) was changed to the IDF-5 and was changed also how the heap management works py/gc & esp32: Add MICROPY_GC_SPLIT_HEAP_AUTO to automatically grow heap on esp32 #12141 - that are two big changes. Can be some of these changes made this new version slowest?

Has anyone experimented the same problem with this new version?

Thank you very much
