[Nepomuk] nepomuk performance

[PierreL]

Hi,

Specs:
sopranocmd --version sopranocmd 2.6.0
Using Virtuoso Version: "6.1.2.3127-pthreads"  
KDE 4.6.3 (4.6.3) "release 4"
Strigi is disabled


***nepomukserver and nepomukservice are consuming 23+% of CPU each constantly all the time. 

>Why is this?
>How can I tweak things?
>How can I see what it is doing?
>Is there a nepomuk performance manual somewhere?

Please ask for more info if needed.

Thanks,
