If your shared hosting reports performance problems, it should take
advantage of caching. Refusing to use the available facilities and
complaining about performance is a little silly. Not all caching options
supported by mediawiki are unsuitable for shared hosts. Some will also
improve the perfomance of the other users, too.

MediaWiki is a fat wiki. Plus some extensions like Dynamic Page List
aren't optimized for many users precisely.
However, it should also be taken into account the number of sites served
by that server and how shitty they hardware is.
