Long GIFs eventually slow down and cause the iexplorer.exe thread that's rendering it to consume a whole logical CPU core.

I can confirm that GIF animation is finally performing well in IE11 RTM that is included in Windows 8.1 RTM.

I can repro this slowness in IE10 RTM, Chrome 25, and Firefox 19 on Windows 7, but it doesn't take high CPU usage.
But this slowness only happens for the first time, as it seems the GIF file is streaming video data in the background. The lag could be caused by slow internet connection (bandwidth issue).

I got 100% CPU usage on a single core AMD Athlon 64 Venice, 2288 MHz (11 x 208) and HD4670 AGP
Firefox Nightly , Opera Next and Chrome Canary are working fine.
