nperf

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

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

Differences to iperf3

• 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
