Title: Forum issue: Lockup with posts containing large images
Post by: tarbat 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.

Same here, IE8 25% on scrolling.

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.

We have noticed it before and have advised SMF (the created the code for the forum) on the issue and awaiting to hear back from them.

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