I doubt it's the latter.  I haven't used KMail in a few years, but here's 
some things to look at: 
 - if your home dir is on NFS, and you don't have the NFS locking daemon 
working, things that need to lock usually fall back to a very inefficient 
locking method. 
 - change the format of the mailbox.  If it's currently mbox, try it as 
maildir (or visa-versa).  See this for some fun discussion:

I wonder what the issue was specifically, since the kernel has been 
incorporating a lot of the low-latency/real-time patches lately, mostly in 
the name of audio support.  To me, that seems like probably the same type of 
stuff the kernel would need to manage UI response times...
