Hi Anis,

Are you possibly running other CPU-intensive tasks on your machine at the same time?

I can't seem to repeat your problem over here - on my 5-year old system with a single 2.4GHz CPU, it takes 27 seconds to finish doing a Boolean Difference of all the buttons from the main phone body, using the Jan-19 v2 beta with the file you posted.

This system is pretty old now, and it was not even a high end machine at the time.

You may want to take a look at your system and make sure there isn't any bad software that may be running in the background taking up a lot of CPU time.

Another possibility is that your laptop may be running in a special "conserve power mode" where it runs at a slower CPU speed in order to prolong your battery life. You may want to plug in your laptop to a power source to possibly help avoid this.
