very slow loading pages

very slow loading pages

As soon as I upgraded Opera 12.00 I noticed a huge difference in page load times. Slow throughout the whole loading process. I had to quit using opera for a game I love it was so bad. Kind of a big deal because I've done massive userJS work to the interface. No the problem is not from userJS, moved files to a temp directory where they would not be executed. Other browsers, Firefox and Google Chrome, are loading pages fine.

Also running ~49% cpu usage, with only 9 tabs open. No major web applications loaded either. At least the freeze-ups may have stopped, honestly I haven't used it enough to verify. I'm really not the Opera fanboy I used to be

Can you try running with a clean profile to see if it's an issue with your settings ('opera -pd ~/opera-clean' should work)?

If it works fine with a clean profile, some settings you could take a look at in your own profile are
- hardware acceleration (experimental feature, turned off by default, turning it on will slow down most things and speed up some things)
- Delayed Script Execution (pre-Opera 12 feature, turned off by default, that has been superseded by new page loading code, but pref is still there and can interfere)

Other interesting data:
- Which sites do you visit? We have a known problem with some web sites with dual IPv6/IPv4 support if you have IPv6 enabled on your machine.
- Which Linux version and distro do you use?

Beautiful, the clean profile worked. I didn't have either of the options you mentioned activated though. I don't use IPv6, but my networking is a mess from trying to share my tethered phone connection. I'm using Ubuntu 12.04.

Having a nasty time trying to get my userJS to run. It's showing up in dragonfly, and will show errors in the console log if I break it, but it will not alter the page. UserJS is checked and the directory is set properly. Same code runs fine with the original "slow" profile.

I also have 64bit Ubuntu 12.04 lts Gnome shell 3.4.1

and Opera 12 is very slow, tabs open slow too

clicking on tabs is also very slow

Hi everyone, I think I do have a so called clean Opera - except the "Clear" speed dial with 16 by 8 pages.
Frequently dialed stream sources or other heavy flash-loaded sites would have been
PRACTICALLY UNUSABLE for years...
If I couldn't feed the address in the (different) back up browser right next.
All Operas on different machines load quickly the good portion of site "elements" - without showing anything or just some of the plain text - and slow down then to almost zero. Few times a week it crashes about it.
To emphasize: I'm familiar with all the updateritis and my AV (ESET ; 2 flawless years) settings are top strict.
Tha backup - a widely used one - worked provocatively straight through the tasks. Always.
I love my Opera beyond any reason but its more and more like clinging on grandpas three legged chair: If you have it dismantled of the beloved covering and refurbished, it looks like the one from IKEA (which I respect by the way).
I don't know nothing about anything but I imagine we'll have kinda binary diagnostic tool which runs at any time necessary before downloading patches.
Or am I the only stupid user unable to use his browser according to its purpose?
