too many gifs in recyclerview

Very slow，and block; but use glide is smooth ,how can i optimize？ thanks too much.

if (uri.toString().isGif()) {

val controllerBuilder =
Fresco.newDraweeControllerBuilder()
.setAutoPlayAnimations(true)
.setOldController(simpleDraweeView.getController());
val optionsBuilder =
ImageDecodeOptions.newBuilder().setMaxDimensionPx(4000);

optionsBuilder.setCustomImageDecoder(GifDecoder())

controllerBuilder.setImageRequest(
ImageRequestBuilder.newBuilderWithSource(uri)
.setImageDecodeOptions(optionsBuilder.build())
.build());

simpleDraweeView.getHierarchy().setOverlayImage(null);
simpleDraweeView.controller = controllerBuilder.build()

return
}
