I'm sure as the size of the database ( number of articles ) increases the wiki will slow down.

What do you base this assumption upon?

Database speed should be nearly log(N). So unless you're doing something really huge, you should not notice much (if any) slowdown with more pages. Increasing your database table size by a factor of ten should only halve the access speed.

I remember looking at an application that allowed you to delete all versions in the history except the most current one. Will this help?

I don't see how this will help performance much, except for things that deal with history, which would then be broken anyway. So don't use history features, and it won't slow you down for reading! (Yes, writing is impacted by history, but again, it shouldn't be much.)

Right now I'm running the app on a shared system.

That may be the problem!

Have you checked other things? What's your load average? What does top (1) say? How full is your network pipe? What is your network latency? Is MySQL overloaded with other apps accessing it?

These (and others) are things you should start examining before assuming MediaWiki has anything to do with it.
