The Performance Analyst is a Python package for timing snippets of Python code. The results can be stored in a database and postprocessed using a command line tool. This is useful for tracking the performance of Python software over time. A tool called pa.py is supplied which can be used to query and manage the database contents and to create plots of the performance results.
The performance is measured by the amount of wall clock time and CPU time in seconds.
The software is modelled after the Python unit test library, which makes it easy to use if you are familiar with that. The terminology is similar to the terms used in the unit test library:
| term | Description |
|---|---|
| timer case | A method which contains the code that needs to be timed |
| timer suite | A class in which related time cases are aggregated |
| timer loader | Loads timer suites and their associated timer cases |
| timer runner | Executes all test cases and handles the results, like storing them in a database |
