Features

• Network Throughput Measurement Tools - Quantifies maximum data transfer rates, latency, and packet loss across TCP, UDP, and ICMP protocols.
• Network Performance Benchmarks - Measures maximum throughput, bandwidth, and connection rates across TCP, UDP, and ICMP protocols.
• Self-Hosted Servers - Hosts a private listener that accepts incoming performance tests and displays the results.
• Network Performance Analyzers - Calculates bandwidth, jitter, and connection rates between client and server endpoints to analyze performance.
• Measurement Endpoint Hosting - Listens on specified ports for TCP and UDP traffic to serve as a measurement endpoint.
• Multi-Protocol Performance Tools - Analyzes throughput, latency, and packet loss across TCP, UDP, and ICMP protocols.
• Network Latency Measurements - Tracks the time data takes to travel between endpoints and the variation in that delay.
• TCP Connection Health Diagnostics - Identifies network instability by tracking TCP retransmissions and analyzing connection health through system statistics.
• Retransmission Tracing - Extracts TCP segment retransmission counts from the operating system to identify network instability.
• Network Statistics Extraction - Extracts raw network metrics and TCP retransmission counts directly from operating system control files and interface counters.
• OS Network Metric Extraction - Extracts TCP-specific statistics from the operating system to analyze connection health.
• Jitter Analysis - Measures round-trip time, packet loss, and jitter to evaluate the stability of network connections.
• Network Diagnostic CLI Tools - Provides a terminal-based interface for mapping network paths and monitoring real-time interface statistics.
• Network Interface Statistics Collectors - Collects transmit and receive packet and byte counts from active network interfaces.
• Network Latency Testing - Tracks round-trip time, jitter, and packet loss to evaluate the stability and delay of network connections.
• Network Statistics Tracking - Tracks network device throughput and TCP retransmissions over specific intervals for real-time analysis.
• Parallel Bandwidth Saturation - Uses concurrent connections to saturate network bandwidth and determine maximum packet and connection rates.
• Client-Server Deployment Modes - Allows executing server and client operations in a decoupled configuration across different hosts.
• Asymmetric Path Analysis - Executes reverse tests from server to client to identify performance differences between upload and download paths.
• Route Tracing - Maps the route packets take to reach a destination to diagnose routing issues.
• Network Protocol Testing - Compares network behavior and speed across different versions of IP and encrypted HTTPS connections.
• IP Version Filters - Restricts network tests to IPv4 or IPv6 to isolate protocol-specific performance bottlenecks.
• Network Troubleshooting Tools - Maps the route packets take to a destination to diagnose and resolve routing and connectivity issues.
• Packet Rate Benchmarking - Calculates the total number of packets transmitted per second over a network using specific packet sizes.
• Traffic Shaping - Controls network tests by enforcing specific IP versions or using SSL encryption to isolate performance bottlenecks.
• Massive Connection Rate Generators - Determines the number of successful connections per second a server can handle via parallel sessions.
• Domain Connectivity Tests - Runs connectivity tests such as ping and connection rate checks against remote servers.
• Network Bottleneck Diagnosis - Analyzes socket states and transmission limits to locate network throughput bottlenecks.
• Real-Time Network Monitors - Collects real-time interface statistics and data rates to monitor bandwidth usage and identify bottlenecks.
• HTTPS Performance Testing - Measures network throughput over encrypted SSL/TLS connections to evaluate encryption overhead.
• Asymmetric Path Measurements - Initiates TCP performance measurements from the server back to the client to identify asymmetric paths.
• Command Line Tools - Listed in the “Command Line Tools” section of the The Book Of Secret Knowledge awesome list.
• Network Security - Network performance measurement tool for TCP, UDP, and HTTP.
