If you need a thumb rule, you usually choose multiple instances over single. Downside is, I think, it only uses little more memory. But else than that multiple instance is much better choice.
I ran into exactly same issue. But I changed my application instead of running it multiple times. I separated databases for each users then routed them accordingly. Edited some logics but now every user has their own "workspaces" but single app. It is much easier now to develop & maintain. This also could be an option.
