librespeed/speedtest

Features

• Self-Hosted Servers - Provides a private server for measuring download and upload performance without relying on third-party services.
• Network Throughput Measurement Tools - Quantifies download speed, upload speed, ping, and jitter to evaluate the current quality of an internet connection.
• HTML5 Implementations - Implements network speed, ping, and jitter measurements using HTML5 and browser APIs.
• Multi-Region Speed Tests - Executes performance measurements against several different server points to compare network speeds across different regions.
• Round-Trip Time Measurements - Synchronizes timing and data requests between the browser and server to accurately calculate round-trip time and jitter.
• Throughput Measurement - Calculates network throughput and latency by timing the transfer of data chunks via browser APIs.
• Internet Performance Monitors - Tracks ping, jitter, and bandwidth over time to identify network instability or service provider performance drops.
• Telemetry Persistence - Persists test results and connection metadata to a relational database for historical analysis and reporting.
• Test Result Persistence - Stores test results and connection metadata in a database for auditing and long-term trend monitoring.
• Anti-Compression Payload Generation - Produces random data streams on the server to prevent compression algorithms from inflating download speed results.
• Connection Metadata Tracking - Identifies the user IP address, internet service provider, and physical distance from the test server.
• Multi-Datacenter Coordination - Synchronizes timing and data requests across multiple remote endpoints to compare network performance and latency.
• Network Performance Analysis Tools - Executes network tests across different server environments and geographic locations for routing analysis.
• Random Binary Generators - Generates random binary data on the fly to prevent compression from skewing download speed measurements.
• Stateless Network Probes - Uses standard HTTP requests to send and receive data buffers without requiring persistent socket connections for tests.
• Language-Agnostic Measurement Layers - Implements core measurement logic across both PHP and Node.js backends using a consistent interface.
• Telemetry Collection - Gathers network performance metrics and test results in a database for long-term analysis.
• Telemetry Collectors - Records connection metadata and performance metrics into a database for historical analysis and reporting.
• Interchangeable Backend Implementations - Provides the capability to swap the entire backend implementation between PHP and Node.js while preserving functional behavior.
