 No, in fact I believe changing owner_events to True makes KWin loose some 
events, which may explain the speedup for you. I'm afraid this is too 
complicated issue to do to change it now. And even after 3.2, I think a 
proper solution would be compressing some events inside KWin, more than it's 
done now.
