There are bottlenecks in nepomuk, but there are in V as well.
Once upon a time, I did some benchmarks with sql (sqlite) and sparql
(virtuoso/soprano) queries for the things that are needed in kamd - the main
being 'get all events from that to that timestamp, that belong to this
application in that activity'. While the query in SQL is a simple filtering on
a single table, in sparql it is a couple of joins.

Agreed. Though the article looks quite interesting :)
I think that people tend to see nepomuk too much as a kitchen-sink database
and are pushing all kinds of junk data into it. Instead of just the data that
should be shared with other applications.
Cheerio,
Ivan
