Hi Uday, this seems to even happen for a message of the type
Content-Type: text/plain; charset="ISO-8859-1"
with no attachments and a length of about 100 characters.  as far as I could 
see the slow part is in the following lines at the very end of 
vm-decode-mime-message:

  (vm-display nil nil '(vm-decode-mime-message)
              '(vm-decode-mime-message reading-message)))

although I couldn't go beyond that in spite of several tries. thanks for the 
ideas below, they don't exactly address the issue, but it's not critical in any 
case.  cheers, E
