My current implementation in PHP is doing the caching only per request,
that could be a little bit faster. But if the caching is done in the
application context I wouldn't expect performance problems.

If a filter would have a one to one relation with a statement I would
accept this argument, but a filter could match also to a set of triples.
Maybe even a regular expression or namespace filter makes sense.
