Opera pre-Alpha 12.00 Build 1065: Volatile high CPU usage at web page.
Usually high CPU usage at this web page :bloom.bg/pl1E4Z
I can get up to 97% CPU used up by Opera with the fully loaded web page in question. I have a old Pentium 4 2.53 Ghz processor. It also noticeably reduces the responsiveness of the browser. It can go as low as 6% CPU usage all the way up to 97% (even higher), CPU usage on the same page fully loaded usually when I move scroll the page. I also had a major incident using google images, where the web page loading would stall, the browser becomes completely unresponsive.
Here is a couple of snapshots of the incident in question at 52%, then up to 97%, I even seen 99% CPU usage.:

I have Windows XP Professional SP3, 1 Gigabyte of RAM, Pentium 4 2.53GHz CPU with a Nvidia 5500 GPU. Yes I have a old computer. I also recently installed AVG Free Edition just letting you know.
Yeah I have also notice sluggishness and random freezing with Opera 12.00 build 1060 and 1065.
Till now I didn't bothered to list the webpages where it happens but I will do it from now on and post the link for the developer
teams to investigate further
Sometimes while browsing opera just stops responding to keyboard or mouse clicks accompanied with high CPU usage. Most of the time I had to kill browser instance and sometimes after closing all other applications it starts responding but closing down is not possible every time.
One more observation I have made that opera loads DXSound.dll with "TimeCritical" as thread priority and open mswsock.dll with "Above Normal" thread priority. If I manually change the thready priority to "Normal" Opera does becomes responsive at times, though it does not happens all the time.
Does opera request to open DXSound.dll with "TimeCritical" and mswsock.dll with "Above" Normal thread priority or it is the OS itself that creating threads with those priorities.
I am running Windows 7 Ultimate 32 Bits + SP1
Thanks
