iPerf3 Command Generator – Smart Speed Test Script Builder

Enter your server IP address – The tool automatically detects your location and recommends the closest iPerf3 test server based on geographical proximity.

Choose from available iPerf3 servers and ports – If a server supports multiple ports, you can manually select the port you prefer for your test.

Select TCP or UDP protocol – Use TCP for reliable, connection-based testing or UDP for maximum throughput and jitter/loss measurements.

Customize test duration (-t) – Choose how long you want the speed test to run (e.g., 10, 20, 30, or 60 seconds).

Set your desired bandwidth (-b) – When using UDP, you can define the maximum traffic rate in Mbit/s or Gbit/s.

Enable IPv6 – Toggle this option to run your test over IPv6 instead of IPv4.

The generated command is fully compatible with Linux terminals and ready to copy and paste.
