B4R Question Compiling time ESP8266

Note that it is actually Arduino IDE command line tool that compiles the project.

On my PC first run takes:
Compiling & deploying Ino project (Generic ESP8266 Module - COM4) (43.14s)

The following compilations are a few seconds quicker.

Yes, Erel, thanks for test - my Arduino IDE itself is also slow, almost the same 2.5...3 mins to compile any ESP8266 project, but any native Arduino board project is compiled much more faster.
What is your ESP8266 board version in Arduino's Board manager? My was 3.0.0, and now 3.0.1, both slow.
But i see that 3.0.2 is available to install, but impossible to install.


And how to check the compiler version ? I guess, if compilation is slow - it should be the compiler itself.

upd. v.3.0.2 is installed OK via correct link "https://arduino.esp8266.com/stable/package_esp8266com_index.json", and the compiler "C:\Users\VLAD-HP\AppData\Local\Arduino15\packages\esp8266\tools\xtensa-lx106-elf-gcc\3.0.4-gcc10.3-1757bed" is installed

but no better speed

ESP8266 is indeed much slower than compiling to Arduino.
It was always like this.

I'm using Arduino IDE 1.8.15 and ESP8266 v3.0.0.

Ha ! Solved by such way:
1) Installed ESP8266 board of latest version 3.0.2 - it's slow compilation.
2) And after it - re-install ESP8266 board to previous v.2.7.4: board files are still of latest v.3.0.2 preserved, but the compiler now is again old C:\Users\VLAD-HP\AppData\Local\Arduino15\packages\esp8266\tools\xtensa-lx106-elf-gcc\2.5.0-4-b40a506\

And moreover - the old RTC code exception now is again working OK !
And compilation is 1.5 mins only !!! Solved.
