iperf - Bandwidth measurements

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 s tuning of various parameters related to timing, buffers and protocols (T, UDP, SCTP with IPv4 and IPv6). For each test it reports the bandwidth, loss, and other parameters.

iPerf features
✓ T and SCTP
Measure bandwidth
Report MSS/MTU size and observed read sizes.
for T 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 T slowstart (-O option).
✓ New: Set target bandwidth for UDP and (new) T (-b option).
✓ New: Set IPv6 flow label (-L option)
✓ New: Set congestion control algorithm (-C option)
✓ New: Use SCTP rather than T (--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)
