Also how is this correct behavior dammit? This wall of Opera just doesnt seem right and I have 6 tabs open.

The first one has tendency of going a LOT higher when Opera decides to actually do something.

Thanks for the suggestion, but unfortunately it didnt help.

I registered just to post here about the same exact problem with Opera Im having, which noone seems to care about. I have the latest version 26.0.1656.32 and from about version 25 using Opera is a horrible experience for me. Anything I do with it, it takes time. Opening? 15-30 seconds. Oh yeah and it crashes a few times too (this is actually getting worse with each update of Opera since 25). Opening a new tab? 4-6 seconds. Closing a tab? The same. Also Opera just "freezes" every minute or so while scrolling, typing, watching youtube.
I dont have any extensions and I tried to disabling harware acceleration to no effect. I have an Intel i5-3350P, 8 GB of ram and a SSD drive. I can be playing newest games or using other browsers without problems while Opera would be going to hell at the same moment. And no, Im not going to try beta or dev versions because hell, if I would want dig through internet finding out which version of software works, I would be using Linux in first place. At home I use computer for fun, not to feel Im at work again. So all I want to know is, is this going to be fixed soon, or am I free to dump Opera after many many years?
