Speeding up compile time

It’s taking around a minute to recompile changes to a tiny amount of code. My CPU and hard drive are barely being touched. Is there any way to speed this up? I saw you can do “/MP 11” in the command line settings to force VS to do parallel file compilations, but I wasn’t sure where to add it. I ended up adding it after the Build/Rebuild All options right after “-rocket”. No idea if it’s made a difference. Advice?
