You can do a few things to get it sorted, at least in my experience. In 
System Settings, Desktop Search, increase memory to 350 Mb or more.

Then edit the file
/HOME/.kde/share/config/akonadi_nepomuk_feederrc
to set the lines
InitialIndexingComplete=false
and
DisableIdleDetection=true

Before that do from command line "akonadictl stop", after do "akonadictl 
start". Then leave the computer on over night or so as it will be 
burning CPU. For how long depends on the size of your mailfolders.

Following that I have a nice quiet PC that only does a "virtuoso check" 
on login.

Best
Sinclair
