Profiling
This project is a performance analysis suite for Python applications, providing tools for both application-wide profiling and granular code benchmarking. It enables developers to identify execution bottlenecks and measure function call frequency through a combination of deterministic tracing and statistical sampling methods.
The tool distinguishes itself by offering a terminal-based interactive interface that allows for real-time navigation and filtering of complex call stacks. It supports non-intrusive data collection through signal-based process interception, enabling performance monitoring without requiring modifications to the application source code. Users can also trigger profiling logic programmatically based on specific runtime events or custom conditions.
The suite covers a broad range of observability tasks, including continuous monitoring of long-running services and the generation of detailed performance reports. Captured execution data can be serialized into a binary format for offline inspection, facilitating long-term performance tracking and regression analysis across development cycles.
