Features

• HTTP Load Testing - Provides a high-volume HTTP request generator to measure the performance and stability of web services.
• Libraries - Provides a programmable package for integrating high-performance HTTP request generation into other applications.
• Command-Line HTTP Clients - Ships a command-line utility for sending a constant rate of HTTP requests to measure latency.
• Request Rate Controllers - Implements a constant-rate request scheduler to maintain a fixed frequency of requests regardless of target response times.
• Constant-Rate Request Schedulers - Implements a timing loop to dispatch HTTP requests at a fixed frequency regardless of the target response time.
• Distributed Load Generation - Scales load tests across multiple machines to simulate high-scale traffic and bypass single-node hardware limitations.
• Performance Analysis - Evaluates request latency, success rates, and throughput using reports and histograms to identify bottlenecks.
• Performance Testing - Subjects web services to high-volume traffic to evaluate stability and responsiveness under pressure.
• Load Testing Tools - Sends a configurable rate of requests to target URLs over a specified duration to measure performance.
• Steady-State Generation - Generates a steady stream of HTTP requests at a fixed frequency to measure system performance.
• Results Analysis - Generates text, JSON, and histogram reports from captured data to evaluate latency and success rates.
• Binary Serialization Formats - Writes raw test metrics to a compact binary format to minimize disk I/O and storage space.
• Time-Series Visualizers - Creates interactive HTML plots and time series graphs to analyze response time changes over the duration of a test.
• Lazy Target Streaming - Reads request definitions from files or standard input as a stream to keep memory usage low during large tests.
• Latency - Calculates success ratios, throughput, and latency percentiles from result files for performance evaluation.
• Metric Aggregation & Downsampling - Reduces large result sets into smaller data points using moving averages to render interactive plots.
• File-Based Target Loading - Reads target lists from files or standard input and distributes requests across them using a round-robin strategy.
• Round-Robin Target Distribution - Cycles through a list of target endpoints sequentially to distribute load evenly across multiple specified URLs.
• Structured Target Specifications - Allows defining request methods, URLs, bodies, and headers via a structured schema for execution.
• Request Payloads - Supports defining target requests using JSON, HTTP, or plain-text formats to specify payloads.
• Decoupled Architectures - Separates the request execution phase from the reporting phase using interchangeable result encoders and decoders.
• Performance Reporting - Produces HTML5 plots, text histograms, and CSV records to analyze request latency and throughput.
• Prometheus Exporters - Exposes internal performance counters via an HTTP endpoint for Prometheus scraping.
• Dynamic Target Streaming - Supports streaming request definitions from external programs or files in HTTP or JSON format to simulate varied traffic.
• Test Reporters - Transforms raw load test data into structured formats to simplify downstream reporting.
• Performance Test Visualizations - Transforms raw test data into visual plots for detailed analysis of latency and throughput over time.
• Performance Testing and Analysis - Provides a toolkit for converting load test results into CSV, JSON, and interactive HTML latency plots.
• Load Ramping - Executes tests at increasing request rates to analyze how latency and success rates change under escalating stress.
• Test Result Converters - Transforming result files between various data encodings to facilitate external analysis and data processing.
• Web Traffic Simulators - Mimics high-concurrency user behavior to test the resilience and stability of web services.
• Target Endpoint Mapping - Specifies target URLs and methods using plain text, JSON, or streaming input to determine endpoints for stress testing.
• Infrastructure Tools - HTTP load testing tool and library.
• Command Line Tools - Listed in the “Command Line Tools” section of the The Book Of Secret Knowledge awesome list.
• HTTP Security - Load testing tool for constant throughput benchmarking.
