if you reduce the memory usage it will take longer...

nope, depends on available ram. your main enemy is disk io. for example if a one core compilation stay on ram will be faster that 16 core full speed compilation which involve virtual memory.

If you don’t have enough ram it will attempt to use IO, but it uses the ram it requires. I don’t think reducing the memory usage and compute more will be faster than the IO penalty

that's for cl not the msbuild, with cl directly it needs a lot out of sln configs

it seems that ue4 source code in windows has a complex undocumented config system, their sln works internally with make files and some custom selfdocumented configs in c#. maybe that's why msbuild config does not work. still i did not find a unified make file and in their c# configs there is nothing about compilation threads/processes. if you know something about their config system please let me know.
