There is only one call to BoonEx during license registration, and NO requests to BoonEx after this (except some rear situation like domain changing).
So load time is not suffering from it at all !

Also It was not mentioned here that Dolphin license is Creative Commons Attribution 3.0 License -
Below is the legacy version of the Boonex site, maintained for Dolphin.Pro 7.x support.
The new Dolphin solution is powered by UNA Community Management System.
