nperf

A portable network performance measurement tool for TCP/UDP/QUIC protocols. Similar to iperf3 in usage.

Supported on Linux and Windows. (macos coming soon)

QUIC protocol testing uses the quinn QUIC implementation. Future support for Quiche is WIP.

Differences to iperf3

• nperf works on Windows
• QUIC is newly supported in nperf
• Some CLI options yet to be supported in nperf and some are WIP
• SCTP is unsupported
• No support for --bidir

Usage

More options available via help.

Server

```bash

binds to [::]:8080 by default

cargo run -- -s ```

Client

```bash

connects to 127.0.0.1:8080 by default and test TCP streams

cargo run -- cargo run -- -c 127.0.0.1

Test UDP performance

cargo run -- -u

Test QUIC performance

cargo run -- -q

Test with parallel streams using -P, period to test with -t

cargo run -- -u -P 2 -t 30 ```

Future

• Support for TCP congestion algorithm, send/recv buffer sizes
• More performance metrics like rtt, retransmits, congestion window, etc
• More performance and configuration options for QUIC
