I am building c++ from the source. I have done this a few times now, and it always seems to take a few hours. (4+) This seems very long. Especially since I am using a decent system. I Got an SSD, 12 cores (20 logical), and 32 Gb of ram.
What I am noticing is that my actual CPU usage is strange. Out of the 20 logical cores, 16 are close to idle or even parked. And four are running at 100% all the time.
I am using Fastbuild. And in there, I can see that it uses 19 cores. And that some of the files take 800+ seconds to build.
Does anyone have any idea what is going wrong? I would appreciate some help.
