It is very slow, i used it for my website. I tested using pingdom tool
here are the results of with or without Wp Thumbie plugin installed

With WP THUMBIE
Page load time: 5.79seconds
Wait time(server response time): 3.49 seconds
Without WP THUMBIE
Page Load time: 3.00 Seconds
Wait time: 686 milli seconds

its clearly very fast while not using WP Thumbie.

To confirm i used P3 profiler, WP Thumbie was taking 51% of the time, there is a 50% increase in speed after deactivating the plugin.

Moreover, i was not really using the plugin, it was just installed and active.

Works, but really kills performance with 3x the mySQL DB queries per page load. Our site went from .5 second load time to over 15 second load time with this one plugin. Shut it back off and speeds returned.

There are many other better options that are more up to date than this one.
