After some weeks of testing (and fixing the mqtt lag issue BIG THX @ascillato ) it is stated, pre 2.6 core is better than core 2.5.2.
The pre core 2.6 differs from main Arduino repo. Two additional PRs added (PR which frees >600 bytes iram and PR which fixes mqtt lag)
Main benefit core pre 2.6. fixes mqtt reconnects of cores 2.4.x. and 2.5.x
Switch default FW to "2.2.2-dev(38a443e)" (menu:2.2.1+100)
* enable by default latest 2.2.x firmware, including fixed espnow
* LittleFS: avoid crash when FS size is 0
* flash size defaults: 1M for generic board, not empty FS for all
When using TLS, this flag avoids loading all the Elliptic Curves algorithm, and saves ~45KB of flash. Anyways, Elliptic Curves are far too slow for ESP8266 and the handshake would take more the 5 seconds. With this flag we limit to RSA algorithms which are faster.
Thx for the tipp @s-hadinger
