Gifs on Photoshop are better quality and way less heavier than those made on After Effect. In case people still wonder why their gif is still slow while using photoshop : First you are doing it wrong : you are not setting the framerate but you are setting the delay time for each frame. You can stil get the result you want but its way more complicated. The method since Photoshop cc2015 (at least) When you click on Window > Timeline you are working with the "Frame Animation" Once you are done with the animation of your gif you must convert it to "Video Timeline" (click on the lower left corner tab, in your Frame Animation window, just next to the loop setting (once, 3 times, forever). Then click on the tab to the right corner of the timeline : the timeline setting. Click next on "Set Timeline Frame Rate..." Lower the framerate to get your animation faster, and higher is you want is faster. Hope it will help.
