Ethr is a cross-platform network performance measurement tool written in Go that measures bandwidth, connections/s, packets/s, latency, loss, and jitter over TCP, UDP, HTTP, HTTPS, and ICMP. It unifies the functionality of tools like iPerf3, ntttcp, psping, sockperf, and latte into a single client/server tool.
Use cases
- measure tcp and udp bandwidth between two hosts
- test network latency and jitter
- benchmark connections per second on a server
- measure packets per second throughput
- cross-platform iperf3 alternative for windows and linux
- measure tcp connection setup latency
- run network performance tests with many concurrent threads
When to choose
- you need one tool for bandwidth, latency, and connection-rate measurements across platforms
- you need high thread/connection counts (1024+) or multiple clients against one server
- you want a native cross-platform tool without cygwin or compilation hassle
When to avoid
- you need iPerf3's richer options like throttled testing or advanced traffic shaping
- you only need simple ping-style checks
- you need protocol support beyond TCP, UDP, HTTP(S), and ICMP
