Benchmark Python Snippets Online

Perfpy allows you to benchmark python snippets online and share them with other people. You can measure the performance and memory usage of code on different python versions in this sandbox environment.

The tool can compare and test the speed of 3rd-party libraries or library versions, so you can find out which is the fastest or consumes less memory between numpy, opencv, scipy and pandas for a certain function.
