Unfortunately our delete performance is not stellar. The planned
revision of the store layer that we anticipate providing at least one
more order of magnitude in insert performance will also address
this. Unfortunately this is at least 9 months away, probably closer
to 18. Of course there is the added advantage that if your data-
sources are already queryable then you might not have to insert at
all, as we support pluggable resolvers that can provide a real-time
interface to the rdf-mapping of external data. We already support
access to URL addressed rdf datasources, file-system metadata, mp3
id3 tags, and various virtual graphs (xsd, data-type, and arithmatic).
