Hello Jesse!
Speaking of performance questions - some of them were discussed during
ISWC2010 by
Daniel M Herzig, Basil Ell in their paper Semantic MediaWiki in Operation:
Experiences with Building a Semantic Portal. [1]

The performance problems that Wikia has with SMW are very real, even if
caused in no small part by the SMW configuration that is used on the
sites. In any case Wikia runs the largest SMW installations that are
around today, with millions of facts in single databases and complex

We are currently cooperating with Wikia for helping them to improve

Hello ***,
Thanks for contacting Wikia. Semantic MediaWiki is a very powerful
extension. It can let you do some great things on a wiki, but that
power
comes at a cost. Queries can make wikis slow, which can be
frustrating for
visitors. Often, there are less costly extensions or built-in
methods
to
achieve the same effects. So please consider your request for
Semantic
MediaWiki further. A comprehensive guide can be found at
http://semantic-mediawiki.org
Even if you do know you need Semantic MediaWiki for a specific
task,
we
still strongly urge you to take a minute to read the guide.
If you want to go ahead with this feature, please let us know. Or,
let us
know what you want to achieve, and we will look to see if there is
a
better
way than Semantic MediaWiki.

Right, this also shows that there are different types of problems on
different sites. The issues in the portal were mainly relating to the
time needed by MediaWiki for parsing long result lists, and were
alleviated by better caching and pre-formatting of query results.

Markus and Tim, can you be more specific here?
The information I have has been sent to the developer list before by
Eloy. The two main performance problems are slow queries (MySQL goes
into endless computation and memory consumption when SQL queries get
long) and too many write operations (this may include writing of
temporary tables that SMW and extensions like SD may create).
We hope to have concrete solutions for these issues soon. For now, users
with such large sites and communities should consider restricting the
maximal size of queries below SMW's factory limits. Doing this is much
harder once you have given your users the option of using larger queries ...
Cheers,
Markus
