Install: brew install nuttcp

About:
Nuttcp is a highly portable, open-source tool designed for measuring network throughput and performance metrics. It provides precise control over test parameters like packet size, duration, and protocol, making it ideal for detailed network analysis. Its lightweight nature allows for easy deployment across various systems without complex dependencies.

Key Features:

Supports both TCP and UDP protocols
Precise control over packet size and test duration
Provides detailed metrics including throughput, jitter, and packet loss
Highly portable with minimal dependencies

Use Cases:

Measuring maximum bandwidth capacity of a network link
Diagnosing network congestion and performance bottlenecks
Validating Quality of Service (QoS) configurations

Alternatives:

iperf3 – iperf3 is more widely known and features a client-server architecture, whereas nuttcp can operate without a server process for UDP tests.
ping – ping measures latency (round-trip time) but does not measure sustained throughput or bandwidth capacity.
