Thanks for the info Dan. Yes, sesame was not being built as it could not
find the JNI. I'll give Nepomic a ago with sesame installed now.

</div>Well, Nepomuk itself should not use much cpu. There is strigi the desktop<br>
search indexer which writes its data to Nepomuk.<br>
<br>
During the indexing Nepomuk takes quite a lot of CPU.<br>
<br>
To optimize it:<br>
<br>
- Make sure that you are using the sesame2 backend for Soprano. The redland<br>
backend is really slow and so slows down the indexing a lot.<br>
<br>
( when you run sopranocmd it should output something about found plugin<br>
sesame2 when you are using sesame2)<br>
<br>
- In the Nepomuk settings in KDE you can say Strigi what folders to index and<br>
what not. With less folders it is faster ( ;-) ok thats obvious)<br>
<br>
- For now you can disable strigi in the Nepomuk setting at all. There is no<br>
enduser ready way to query the data yet anyway. You can still use the \
other<br> Nepomuk features in Dolphin and other applications ( not much released \
with<br> Nepomuk features at the moment) with disabled strigi but enabeled \
Nepomuk.<br> <br>
- With kde 4.2 you should hopefully be able to only let it index when you are<br>
on AC power.<br>
<br>
- You should also keep in mind: That only the first index takes some time (with<br>
a lot of files it could be a few hours) later scans to update the data should<br>
be a lot faster.<br>
