 * Hi,
 * I noticed that after images uploaded to wordpress, it will take a very long time
   to run the post processing until the thumbnails show up, is there any way to 
   speed up the uploading, for example save the original image first, and post process
   all the new uploaded image in certain time period trigger by cronjob?
 * Best Regards

 * That would require a rewrite of the built-in Media Uploader, and I don’t think
   that is likely to happen. There are many who don’t use the full-size images in
   their post, and so they have to have the resized versions available immediately
   after upload with no delay whatsoever.
 * A big cause of this type of behavior is when your theme (or plugins) register
   a bunch of new sizes for WordPress to generate. You can see how many are being
   generated by turning on debugging for EWWW IO, then browsing over to list view
   in the Media Library, where you’ll see the raw metadata with a yellow background.
 * There is a way to unregister some of those sizes if you aren’t using them (won’t
   affect previous images): [http://www.wpmayor.com/remove-image-sizes-in-wordpress/](http://www.wpmayor.com/remove-image-sizes-in-wordpress/)
