A few months later the mail access speed dropped rapidly to levels even slower than courier was before. Does dovecot have some known limits I didn't see? The mail folder is pretty big, some couple 100 folders and approx 100.000 mails all together (5gig space used).

The courier speed was always a little slow, but ok to work with, dovecot was pretty much faster to start with, and is way slower now

Someone came across this problem before? I could find no help/reference in google.

Nope, the most I saw in dovecot are about 2G and never heard of problems.
What version are you working with? What's the filesystem of your server? Are you using the howto configuration or something special?
