"Unlimited users" the website said. At 250 users, my panel slowed to a crawl. At 300, it crashed. Unlimited was a lie. A skeptical British IPTV reseller stress-tests panel limits before reaching them. An IPTV Reseller Panel that claims unlimited users should handle 500 without breaking. One reseller I know asked their IPTV Reseller Panel provider for a stress test report before signing. The provider refused. Red flag. The reseller chose a different panel that published actual benchmarks. That panel handles 1000 users smoothly. The "unlimited" panel's servers would have failed.
The hidden limit is usually database performance, especially with British IPTV where user history and logs accumulate over time. A panel that's fast at 50 users may crawl at 500. A real example: a reseller imported 600 historical users into their British IPTV panel as a test before committing. The panel took four minutes to load the user list. Deal breaker. They found a panel that loaded 600 users in two seconds. The "unlimited" claim without testing cost their competitor months of frustration. Testing saved the reseller from that fate.
