See how much latency your ISP routing adds

Detecting your location...

Estimates based on real-time measurement to nearest Cloudflare edge. Actual in-game ping may differ by ~15ms due to different routing to game servers. Your IP is sent to ip-api.com for city-level location — we don't store it.

How to check your actual ping in MU Online

Command / method No built-in ping display. Use Windows Resource Monitor (resmon) → Network → TCP Connections → find main.exe → note the server IP, then ping it from Command Prompt.
Where to find it

Not available in-game. Must use external OS tools (Resource Monitor or netstat).

What you'll see

Use 'ping <server IP> -t' in Command Prompt to see real-time round-trip latency in ms. The server IP can be found via Resource Monitor or 'netstat -n | findstr :55901'.

If your actual ping is higher than our estimate, your ISP is routing MU Online traffic through a longer path than necessary. That gap is exactly what PingAim optimizes.
