IMAP server is Dovecot 2.2.27 and it is on the same host and this host
is not load by memory or CPU at all.

5-7 seconds were measured by watch :-(
After I wrote you that Network Profiler in browser showed me 3.5 seconds
(lets start from this point, because 5 seconds subjective, sorry)
After I disabled `threads` page loaded in 1.6secs ±
1.6secs it's with tcp and tls connecting time (`waiting` time is 1.2secs
which is very close to 1secs). This is our current situation.

p.s. Thanks, for your help.
