If it is regenerating its index files, and your email corpus is several Gb 
like mine is, this can take half an hour to complete after a restart.  Once 
that is done it should revert to more normal usage levels.  At 9 days 
uptime, kmail's cpu usage is well down in the noise here. BUT!  I don't 
suck my mail with kmail, all that is farmed out to 
fetchmail/procmail/spamassassin & clamav, so all it actually does is pick 
it up out of /var/spool/mail/user & sort it to the correct folders, on 
queue when the mail comes in.  So that part is not accounted for in the 
kmail column.  In 9+ days, fetchmail has used 10.6 minutes of cpu here, 
spamd an hour 10, and clamd just under an hour.  Plumb tolerable IMO.

Cheers, Gene
