This is GMails fail. Corporate server at my job is pretty fast,
there's no any problem with 30+k folders. And I *have* to cut folders
at gmail down to ~10k messages, otherwise it works too slow for me.

Wanderlust does offline search. Of course, it's up to, how to manage
your mail, but I don't like the idea of running IMAP sever at
localhost. I did it, when I was using Gnus, but Wl is far better than
Gnus in the questions of protocol handling.

I did a couple of patches for ESEARCH feature and folders partial
update. If you manage all your mail only in Wl, partial updates
improve speed and reduce traffic quite a lot (this works with all
kinds of IMAP servers). Our corporate server (Zimbra) also supports
ESEARCH, this boosts almost every operation up to several
times. Unfortunately, GMail doesn't support ESEARCH.

Most of custom patches are in my repo only:
http://repo.or.cz/w/more-wl.git

Btw, if you use Wl only, you can safely set wl-summary-auto-sync-marks
to nil.
