In general, shared hosts are best for hosting static content or dynamic
content that is accessed very lightly.  It also depends on the quality of
the host; some will crumple where others would be fine, and some actually
have caching built in.  Finding a better shared host or a VPS is
probably your best option.

If you'd rather try to draw water from stones, take a look at

I would focus on $wgDisableCounters, $wgMiserMode, $wgJobRunRate,
$wgUseFileCache, and the system messages; tweaking those things should
provide the most benefit.
