Opera seems to die if you send a request to a server that doesn't accept connections on a specific port. If a webserver/proxy/etc runs on port 8080, Opera will work fine since it accepts it. But say you use port 21, or in this case 22. http://jeremiahgrossman.blogspot.com:22/ Opera suddenly takes near 100% CPU. Any ideas why? I haven't done much testing like if the rest of the page loads or not, but it's interesting.

<script>alert('Die!');</script>
<meta http-equiv="refresh" content="0">

That pretty much destroys Opera unless the user is smart enough to turn off javascript from the alert box. Even then, if the iframe is hidden it could take awhile to find the source of the problem. Especially if they have saved sessions that Opera uses as default.

On freebsd it took up 13% of the cpu for about 30 seconds.

I take that back, with nothing else running it might, I had other high priority things going on at the time. Seems to take up 40% and just sits there now.

Interesting. It spiked to 100% for me sustained as well. But it never became unresponsive. Very odd.

Gotta love it. http://ha.ckers.org

45% for me.. but if i right click on the page.. or click one of the browser menus (File,View,Tools,etc) it pauses down to 8% .. then back up to 45 if i un-right click

weird. and multiple iframes of different links doesn't seem to make it worse. and what's weirder, multiple tabs of operacrash.html seems to lowwwer the CPU percentage. which doesn't even make sense .-.

Hmm. The first time I did this, everything ELSE became slow/unresponsive but Opera stayed normal. Now everything works fine. I'll try doing something a tad more cpu intensive while testing.

hmz mine spiked about 13%. Have anyone tried on Epiphany?

It was fixed in the last version apparently for Opera.
What is Epiphany?
