Nope, no central Vim manager, they're all independent unless you explicitly make them communicate. Do operations outside of Vim take a long time as well, or just Vim? Can you reproduce it without all your personal config and plugins, too? It's possible one of those is interfering.

I have noticed that Vim can be VERY slow if runtimepath contains network directories...I've moved my config files to my local disk to fix that.

Or maybe you're saving a really huge .viminfo and/or undo file along with the file you're saving?

Note Vim comes with profiling features, depending on what options you compiled with. See :help profile. You may be able to find the culprit using that, but then again, maybe not.
