How does nrf connect multithread?

Hi,the Nordic team
     It only took me ten minutes to compile the whole Matter program yesterday morning, but now it takes me more than an hour to compile the whole Matter program. According to the preliminary judgment, the compilation only uses single-threaded compilation, but this problem cannot be solved by using the current common method. Why is this?

Hello,

Did you watch the build output in the terminal window to see what was taking so long? The cmake build scripts are single threaded, but the compilation of the source files is not. Ten minutes is quite long. My desktop setup isn't particularly powerful, but I'm on Linux, which helps, and building the matter light bulb took 2 minutes and 10 seconds on my system. 

Could you describe your setup? Could it be a problem with the antivirus? 

Best regards,

Vidar

hi,thank you, I doubt that my source files compile or run to single thread, my process is under Windows.
