Internal speedtest result
http://fastpic.ru/view/79/2016/0519/3881d310c0f86c1094b57146ed84c2e2.jpg.html

Current Opera is 39.0.2234.0.
If native adblock is on - pages loaded too slow. If native adblock is off - all ok.
For example: http://hobbygames.ru
With adblock > 20sec, without 3-4sec.
Exception list is cleared.
It happened after last 2-3 updates.

Any ideas?
