iperf - Bandwidth measurements

Tool for active measurements of the maximum achievable bandwidth on IP networks

This application is an iPerf3 and iPerf2 tool which is ported to Android device.

Latest iPerf binary versions:

- iPerf3: 3.13

- iPerf2: 2.1.9. Please prefer iPerf2 when testing network bandwidth.

iPerf is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6). For each test it reports the bandwidth, loss, and other parameters.

iPerf features

✓ TCP and SCTP

Measure bandwidth

Report MSS/MTU size and observed read sizes.

Support for TCP window size via socket buffers.

✓ UDP

Client can create UDP streams of specified bandwidth.

Measure packet loss

Measure delay jitter

Multicast capable

✓ Cross-platform: Windows, Linux, Android, MacOS X, FreeBSD, OpenBSD, NetBSD, VxWorks, Solaris,...

✓ Client and server can have multiple simultaneous connections (-P option).

✓ Server handles multiple connections, rather than quitting after a single test.

✓ Can run for specified time (-t option), rather than a set amount of data to transfer (-n or -k option).

✓ Print periodic, intermediate bandwidth, jitter, and loss reports at specified intervals (-i option).

✓ Run the server as a daemon (-D option)

✓ Use representative streams to test out how link layer compression affects your achievable bandwidth (-F option).

✓ A server accepts a single client simultaneously (iPerf3) multiple clients simultaneously (iPerf2)

✓ New: Ignore TCP slowstart (-O option).

✓ New: Set target bandwidth for UDP and (new) TCP (-b option).

✓ New: Set IPv6 flow label (-L option)

✓ New: Set congestion control algorithm (-C option)

✓ New: Use SCTP rather than TCP (--sctp option)

✓ New: Output in JSON format (-J option).

✓ New: Disk read test (server: iperf3 -s / client: iperf3 -c testhost -i1 -F filename)

✓ New: Disk write tests (server: iperf3 -s -F filename / client: iperf3 -c testhost -i1)
