Forum issue: Lockup with posts containing large images
« on: February 05, 2010, 09:09:43 AM »
Does anyone else have problems on this site with posts that contain very large images.  This one, for example:
http://www.airnavsystems.com/forum/index.php?topic=4292.0

When I open that discussion, IE8 jumps to 50% CPU (a whole core) for about 30 seconds, and is completely non-responsive.

Any attempt to scroll-down the page also results in 50% CPU on IE8.

Not a problem when using Firefox.

Thanks, at least it's not just me.  I guess it's only a problem in IE8.

Airnav, any idea why this site locks up with large images?  It makes viewing/answering posts with large images very difficult.

I guess it would help if people didn't post such large images.  Posting a 2176×3264 image in a forum is not that helpful really, but the site should be able to handle it, or force the image to be resized to something reasonable.

CPU usage increase was negligible w/ Chrome, also ... FYI.
