did you try to watch the processes with the "System Monitor"? in the Process 
Table select on the listbox "All processes, Tree", and you may guess who to 
blame. In my case, akonadi-control owns several sub-processes, none of them 
consume much CPU nor memory (same is valid for Nepomuk - this has been a huge 
improvement), look at the pic in

I wouldn't blame Akonadi, so may be it's a Kontact thing.

By the way, what's your Akonadi set up? I've found the embedded mysql to 
consume more resources than the server, so I changed the default set-up to use 
a MySQL server running on localhost, but this may not be the case for you...
Anyway, this you try with a whole brand new clean .kde user directory? After 
some crashes, I've found this to be the better solution.
