Professional ping test for League of Legends servers
LoL Ping Test Pro is a free tool that measures the network latency (ping) between your computer and the League of Legends servers in milliseconds. Lower ping means a smoother, more responsive and fairer game; high ping causes lag and stutter.
The tool sends successive requests from your browser to the LoL server and measures each round-trip time. From that data it calculates:
No, it is not identical. A browser-based measurement is affected by DNS, TLS and caching. The result is a strong indicator of your real latency, but it may differ slightly from the ping shown in the game client.
