Hi Rodrigo,

In my experience if you do not make all your summary buffers sticky,
WL can spend a lot of time rebuilding the msgdb as you switch between
folders. You might try setting:

  (setq wl-summary-always-sticky-folder-list t)

But this is really just a guess. From your log above it looks like you
have set example sticky, so I could very well be wrong here.

best, Erik
