Well, v1.1+ does case-insensitive searches by converting all mails to UTF-8 first. But it really shouldn't make it that much slower. What OS and CPU is this with?

You could also try if it happens to work faster by compiling Dovecot without iconv support.

I guess there could also be some kind of a bug that you're triggering.
