netperf
A network (TCP-only) performance measurement tool written in Rust. Designed after iperf3's original code.
This still work-in-progress but all basic features are implemented. Key differences from iperf3:
- Uses a different control protocol (not compatible with iperf3's servers or clients)
- Multi-threaded, parallel streams (-P) will be executed on different threads.
- Design simulates realworld server/client applications in terms of work scheduling.
Installation
cargo install netperf
Usage
On one node you run netperf in server mode:
netperf -s
On a client node, you need to connect to that server (you will need an addressable IP address IPv6 is supported).
netperf -c ::1
By default, the test will use a single stream (client sends and server receives). You can control the number of parallel streams with -P
and the direction of traffic with -R/--bidir
Current Limitations
- Does not support configuring MSS, Congestion control algorithm.
- No UDP/STCP support.
- Does not collect extra stats like retransmits, cwnd, etc. (planned)
