It's certainly not something I have seen reported before - I admit I
don't compose emails with massive amounts of text, but I have never
noticed any laggy-ness with the composer - I've just tried a reply to a
550k mail and there was no issues.  How big are the emails? (Easiest
way to see is to add a 'Size' column to the message list window.)

If you reply using a different style - as a test - such as using an
attachment or inline style - is it still a problem. (Use Ctrl-Atl-R to
get a menu that allows the selection.)

Can you see how the system is responding in general - why is evolution
having problems? Is there something else on the system taking CPU time?
Memory?  Is evolution using a lot of memory? Is the system swapping
lots? What are the specs of the system? What GUI system are you using?
