My comment about mounting network drives as local is that all of a sudden, a file move takes a non-trivial amount of time, and may even timeout. Opening a "Windows Explorer" type view and generating thumbnails becomes super expensive.
Naive software, in personal experience, doesn't even work well with modern multi-core, multi-cache CPUs. Even when it's multithreaded, if it wasn't designed with all this in mind, you're better off running multiple processes on a single machine, treating each core (or sometimes pair) as as separate computer.
