In addition to what Ben said, is the network in use at all
during this? For example, are the files Vim is working on
accessed over a network, or (if Windows) is your profile
or home directory accessed over the network?

Possibly you have some plugin that is doing silly things? Use
:scriptnames to see what is loaded, and temporarily remove
anything not essential. If possible, start Vim like this:

vim -N -u NONE -i NONE (files)

Or use gvim in above. If it is now fast, one of your plugins is
responsible. One plugin I know of that shares data between
instances is mru.vim. I have never seen it cause a slowdown, but
I suppose if you had hundreds of Vim instances it might.

BTW using gvim with tab pages is often better than multiple
instances.
