We'll need a short program that illustrates the problem with test images before we can investigate further.

In recent versions of ImageMagick we modified the color reduction algorithm to improve handling transparent colors. GIF requires a binary transparency, either transparent or not transparent. The new algorithm does a much better job of handling transparency but with a cost in terms of processing time. Notice how fast the program runs if you write to test.miff rather than test.gif. If transparency is not required you will get a speed up writing to GIF. Just set the image matte member to MagickFalse before you write the GIF animation.
