Loading GIFs stutter

Why is it very stuttering when I use fresco to load GIF and webp gif, CPU usage is very high, and frame drops are serious, but when I use another image library glide, it doesn't lag? I load a list of gifs of multiple fragments through viewpager, and when there are too many screen gifs, it will freeze, and it is already very stuck to run one on some low-end device settings.
