Animated GIF performance in Safari

Odd - the only time the subject of animated gifs in Safari has come up has been from users who want to know how to STOP Safari playing them!

Animated GIFs will play just fine on your Mac, but they won’t play within Preview, which is the default app for viewing GIF files.

To change the default app for animated GIFs, click the GIF file icon and press Command-I. Under Open With, select your favorite browser (Safari!) from the drop-down menu and then click the Change All button.

I also noticed this today, and it seems that for some reason the frame rate of animated GIFs is limited to 10 frames per second, or a minimum delay of 100msec per frame. This animation should loop every second: http://www.dr-lex.be/tmp/Rotation1Sec.gif
In Firefox it behaves correctly, but if you time it in Safari, you'll see that it takes 5 seconds per loop, because it has 50 frames.
By the way, QuickTime Player can also play GIF animations and it plays them at the correct speed.
It appears this bug is not in Safari itself, but somewhere deeper in some framework. The bug ID is 5815212.

Does anyone know if this is an issue with WebKit? I download nightly builds and use them occasionally, and noticed an improvement in animated gifs compared to Safari, but it's still not quite up to Firefox's speed.

There are a few bugs reported on webkit with regards to animated GIFs. This one seems the most pertinent:

But, as they note there, the problem is not in Webkit but an OS X image library issue instead.

Agreed, that page does not play right.

I have asked others for assistance and will get back to you!

What version of Flash Player do you have?

Audio and a GIF file?
Give me a direct link to a page that has such a combination.

I believe EmSeta was referring to the videos listed on the right of this page:

It also affects mail. Animated gif are super slow when viewed in mail also.
