Scanning dependencies and build time is slow

My problem is when I use esp32dev in platform.ini as default_envs, build time is about 180 seconds.

I have seen multiple cases where the cause of this was an antivirus tool scanning all compiler invocations (C:\users\<user>\.platformio\packages\toolchain-xtensa32 etc) and/or the pio.exe binary and it had 0 to do with PlatformIO.

PlatformIO too slow to build

I went deep contacting the antivirus assistance and we found the problem: there was the antivirus monitoring everytime a platformIO .exe running. Thanks for your suggestion, you was right!
