Click "Users." Count how many seconds until the list loads. If it's over three seconds, your panel is garbage. A performance-conscious British IPTV reseller refuses to tolerate slow dashboards. An IPTV Reseller Panel that takes five seconds to load a user list will take thirty seconds when you have 500 users. One reseller I know timed their IPTV Reseller Panel at eight seconds per page load. Eight seconds, twenty times per day equals nearly an hour weekly just waiting. They switched panels. New panel loads in under one second. That's forty hours per year saved.
The patience killer most accept is lag, especially with British IPTV where resellers check panels constantly throughout the day. Honestly, slow software trains you to use the panel less. A real example: a reseller timed every action in their British IPTV panel for one week. Total waiting time: four hours. Four hours of staring at loading spinners. They switched to a faster panel. Those four hours became thirty minutes. They used the freed time to actually grow their business instead of fighting their tools.
