I'm running quassel in the client-server setup with postgres as backend, left Amarok alone and use postgres for Akonadi. Unfortunately, that doesn't help much. Virtuoso is the real offender here. I don't understand what it indexes. Search in Kmail doesn't work anyway. It never returns any results. I'm in the same boat as O. Sinclair. I /like/ Kontact (and even the Akonadi idea). The features are perfect, but the bugs are too numerous and performance is very, very bad. Here's to hope! </pre></blockquote></div> Nepomuk isn't the database, akonadi is using an embedded mySQL DB, but can use normal mySQL. (not that this is any less confusing) I looked at using sqlite for akonadi but it was buggy as hell, and no good way to convert between DB's. Has anyone upgraded to 4.7.3 or .4? With the exception of spam filters, ask of my many errors and warnings are now gone with the recent nepomuk updates. -- Clay Weber</body></html>
