--- Comment #6 from Carlos Alberto Lopez Perez <clopez at igalia.com> ---
I have uploaded here some examples of large animations where the problem is much easier to reproduce:


https://people.igalia.com/clopez/wkbug/image_animations_big/

With the 5second version of the gif the first time it plays it takes a lot to load and then it plays really slowly  on the first play.. after it finishes the first play it plays at an ok speed (I guess this is because its slow decoding the image frames into memory or something like that?)


With the 5second version of the apng it plays just fine from the first run.


The 20second version of the gif makes thing much worse and the 20second of the apng causes a crash on the webprocess :(


Feel free to download the images to your disk and you will see it makes no difference to load from local disk, the network speed is not to blame here.

I also uploaded mp4 and webm versions of the animations so you can check how they should play.
