+My experience is that the emacs interface is faster than the vim one.\r
+At least I don't have an examples handy where emacs is slower than the\r
+vim interface at rendering a thread. At a wild guess, I suspect it has\r
+to do with how many attachments there are, and the emacs UI being\r
+overenthusiastic about processing attachements.\r
