[mew-int 3122] performance issues

hi,

Latest Mew and latest Emacs24 on sid is working fine but since i
switched from Emacs23 i see a clear decrease in performance.

When switching to the +backups folder for example the messages appear
like 0.3 second delay between them, or when i hit 'n' (for next
message) in summary mode in my +inbox, i have to wait for the cursor
to move up.

i don't see any other performance problems in Emacs24 (and i use it
for lot of things), so i guess it could me a Mew specific problem.

did anybody has experience with a similar version combo?  is it
working for you?  any ideas how to debug?  i watched after
mew-summary-debug but it does not log any problems.  could having less
messages in my +inbox help?

thanks,

Mew version 6.5rc2
