It could be other things then your hosts fault.

If you're using super complicated templates (like things copied from wikipedia.) they can be expensive to parse. A page save involves a parse, where a view might not. So you may want to try saving a page with just a single letter on it. If that is slow, its likely to be something with db, if it is not slow then its not the db's fault (in all probability)

You can also enable Profiling to be able to tell you exactly which part of MediaWiki is slow. That would be able to tell you if its the db taking forever, or something else.

Certain extensions may cause things to be slow as well.
