In general, the whole akonadi+mysqld+resources+kmail subsystem takes huge
amounts of CPU. For instance now I have:

 2397 ... 384m 138m 3088 S  118 ... mysqld                                      
 3048 ... 405m 133m  10m R   99 ... akonadi_mixedmaildir_resource               
 3060 ... 618m 185m  10m S   51 ... akonadi_nepomuk_email_feeder

Where 118+99+51 = 268% is the CPU usage (on a quad-core system) and
138+133+185=456 is the resident (non shared) memory usage.
And this is with nepomuk disabled (why the email feeder is running?).

This doesn't happen only when checking mail. It happens also when a random
folder is opened or even when kmail doesn't seem to do anything useful (or it's
not even running).

If I look at akonadiconsole while the CPU usage is high I see that there is a
very huge traffic between the components. Sometimes it seems to rescan some of
my folders.
