I reduced the number of folders to 450 and it still takes a while to
start, but I am able to read mails after a while.
While reducing the account to 450 folders I removed all dovecot cache
files as well.

With another old instance of evolution (RHEL6) I checked and only
index.log files are generated for subscribed boxes.
With 3.18 all folders, even the unsusbcribed ones get a index.log. This
means evolution scans them all.

I did a CAMEL_DEBUG=imapx and started evolution.
An this shows for example
* LIST (\NoInferiors \UnMarked) "/" "spam-2015-01.bz2"
* STATUS "spam-2015-01.bz2" (MESSAGES 58 UIDNEXT 384 UIDVALIDITY
1423546869 UNSEEN 56 HIGHESTMODSEQ 2)
This is an existing but unsubscribed folder.
Since I started it showed up several times in the log, so evolution
scans for unsubscribed folders repeatedly.

Scanning > 6000 folders like this makes evolution unusable, at least
with a "normal sized" mail server.

Anyone outside with a good idea why this change to scan unsubscribed
folders was necessary and useful?

Everything unchecked except "Show only subscribed folders"

No significant change.
