In php, it is very slow for the magickwand library to generate GIF images for saving or outputting images. Does anyone know why? Because the GD library does not have the GIF animation writing function, all functions are implemented using MAGICKWAND. it is indeed very useful, but I found that GIF images are generated using XDEBUG (the bigger the more obvious) whether it is saved to a file or directly output, it is very slow, when I use the JPG/PNG format, I will not ask the magickwand Library in php to generate GIF format images. it is very slow to save or output images. Does anyone know why?

$ NewMw = newmagickwand ();
Magicksetformat ($ newMw, 'GIF ');
Magickreadimage({newmw,'old.gif ');
Magickwriteimages({newmw,'filename.gif ');
?>
It takes 700 ms to execute the above code !!!
$ NewMw = newmagickwand ();
Magicksetformat ($ newMw, 'jpg ');
Magickreadimage({newmw,'old.gif ');
Magickwriteimages({newmw,'filename.gif ');
?>
The above code only takes 30 ms !!!
------ Solution --------------------
I don't know. it's your server problem.
------ Solution --------------------
Magicksetformat ($ newMw, 'GIF'); it is best to write this sentence as magicksetformat ($ newMw, 'GIF ');
I'm trying to test all the slow operations here. jpg's 0.3 second gif's 0.5 second
