Terrible mess

This plugin didn’t really speed up the site a lot. It wasn’t def. worth all the effort. It also did some terrible problems on our hosting, probably because of all the disc processes running all the time. A gazillion of files and directories was added in the wp-content directory. The plugin uninstall routine is really really poor – all the cached data remained in the directory – waste of space. Now I’m deleting them through FTP like 2 hours and I’m still far from ending, because it’s thousands of thousands of thousands of … files and directories. I had even quite some problems with my job because of this sloppy plugin.
The site was quite large, with a lot of photos etc., but that’s no excuse. The plugin really SHOULD clean all the ?!#$^$% MESS after uninstall. There should also be some warning with this many of dirs and files – this is really not only a few files – which can cause some serious troubles for some people.

Overall – very poor practice for WP plugins. There should be more effort on the plugin itself than on marketing and self-propagation.
