Cody Konior wants to speed up module loading:
One of the more heated ideas is that you should combine all of your scripts into a massive file and execute it once instead. Currently dbatools uses a mix of these techniques in great detail and to great success.
I don’t want to use a single file because I don’t like build the idea of a pre-compile build pipeline for a scripting language, so here’s an alternative and benchmarks of how these techniques stack up (taken on Windows 10 PS 5.1 obviously your results may differ).
Check out Cody’s example.
