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

# binds to [::]:8080 by default
cargo run -- -s

Client

# 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
