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
