Category: Networking

Tags: networking benchmarking tcp performance diagnostics

Install: brew install flowgrind

About:
Flowgrind is a TCP measurement tool designed to analyze network performance characteristics like throughput, latency, and jitter. Unlike simple throughput testers, it provides detailed insights into the behavior of TCP connections under various conditions. It is particularly useful for diagnosing complex network issues and validating Quality of Service (QoS) parameters.

Key Features:

Measures throughput, latency, and jitter simultaneously
Supports advanced TCP options like window scaling and ECN
Provides detailed statistical analysis of test results
Cross-platform compatibility (Linux, BSD, macOS)

Use Cases:

Diagnosing network bottlenecks and performance degradation
Validating QoS configurations on routers and firewalls
Comparing performance of different TCP stack implementations

Alternatives:

iperf3 – iperf3 is a simpler tool focused primarily on raw throughput measurement, whereas flowgrind offers more granular metrics like latency and jitter.
netperf – netperf is an older benchmark suite; flowgrind offers a more modern interface and more detailed TCP-specific diagnostics.
