[kdepim-users] kmail Fast for HTML, but SLOW for plain-text

[Jeffrey D Anderson]

I'm running kmail 1.9.9 from kdepim 3.5.9 on Scientific Linux 5 and I've 
recently noticed a peculiarity in the performance of kmail.

I've noticed this both on IMAP and dimap.

Here is the symptom:  

I click on a message and it appears in the message pane.  I noticed that 
lately it has seemed quite sluggish (perhaps since the 3.5.9 upgrade).  Then 
I noticed that SOME messages display immediately, while others take several 
seconds to display.

Experimentation has shown that if the message body is of type "Plain Text 
Document" ( as reported in the Message Structure Viewer ) the message takes 
several seconds to display, but if it is of type "HTML Document" it displays 
instantly.  This is true regardless of whether I have automatic HTML 
rendering turned on or off.  I've tried turning off custom fonts and custom 
colors to see if that makes a difference.  I've tried turning off or on the 
Message Structure Viewer.  I've tried pretty much every configuration option 
I could find.

I can't find any other relevant variables.  The slow rendering time for plain 
text messages is the same whether the message is one word or many pages.  
Likewise, HTML messages display instantly, whether they are big or small, and 
whether rendering is turned on or off.
