Bare metal machine

I work for a company that has about 30 websites using docker, I work from home a few days a week and found that when loading pages from localhost its very slow. I mostly do front-end work using a Mac Pro.

Would it make sense and speed things up considerably if I ran docker on a bare metal machine?

I have 3-5 motherboards, ram, processors etc laying around so would only cost me the time to build.

Any feedback / best practices would be greatly appreciated.
