      Hi,
      The Opera 26.0.1656.60 (extensions disabled) is very slow for example on this site: http://www.ubuntu.com/phone/carrier-advisory-group
      The same with Chrome 39.0.2171.95 m but WebKit based too the Comodo Dragon 36.1.1.21 and Chromium Secure 36.1.1.3 are 3 times faster.
      The Firefox 34.0.5 and IE 11 are lighting fast here.

      My config:
      Win7 SP1 x64, i7-950, 24 GBRAM, AMD HD6970

      Opera GPU log:

        Website works fine here in Opera Developer. Turn off hardware acceleration and see if that helps.

          Sorry for the unexpected post layout.

          This slowdown occurs when the page is zoomed.

            May be for a test a fresh Opera test profile may giv you more

            1. Open DOS box
            2. Start Opera by enetering the following command:
              "%ProgramFiles(x86)%\Opera\launcher.exe" --user-data-dir="%TEMP%\OPTEMP\
            3. Visit http://www.ubuntu.com/phone/carrier-advisory-group
            4. Set your zoom to desired value
            5. Scroll

            If it is the same problem as before, you have a problem with your graphics card driver on Windows and not with your Opera profile.
