Austin Biscuits

📢 Austin TUI 1.2.0 is now available from PyPI, with the new live flame graph mode 🔥. This is what it looks like when run inside Visual Studio Code. Pause and open files directly in the editor for further inspection 🔍 github.com/P403n1x87/aust… #python

Profiling is a must if you want to write performant Python code. Austin makes it easy.

⏱️ Making a benchmarking script for Austin D҉a҉n҉g҉e҉r҉ Sampler to quantify the recent performance improvements. The screenshot shows the dramatic 📈 increase in sampling rate (higher = better) and a 📉 decrease in sampling speed (lower = better) that shipped with the 3.3 release 🚀

Stay tuned for some more groovy things!

📢 3.4 is out, with Python 3.11 support and the option to output in the MOJO binary format to reduce redundancy in the emitted output! github.com/P403n1x87/aust… #Python #performace

We've just joined the groovy ⭐ 1k party 🎉🍾

🍾 Another number worth celebrating 🤓

Now you can install your favourite CPython stack sampler with pip 🎉 pypi.org/project/austin… #python #performance

PEP 684 has been accepted!!! Expect to see a per-interpreter GIL in Python 3.12. I'm so excited! This has been many years in the making. Thanks to the many people that have helped! Come to my PyCon US talk 2 weeks from today to learn more. discuss.python.org/t/pep-684-a-pe…

Some serious progress with #Python asyncio #profiling. Not super-pretty but at least the coroutine/task stack is reconstructed as best as possible with the information currently exposed by CPython.

Crossing the "gather" boundary. This profile was generated by running this code with #Python 3.11 and a sprinkle of monkey-patching gist.github.com/mpage/ae3dfd09… (more context on the "gather" boundary problem here github.com/python/cpython…)

I hear you folks like sub-interpreters. My next release 3.6 is just around the corner

📢 Memory mode support has landed on the VS Code extension to help you chase after memory leaks 🎉 marketplace.visualstudio.com/items?itemName… #python #performance #profiling

If you rely on pdb for debugging your Python code and find it slow, then consider giving Dragonfly a try github.com/P403n1x87/drag… #python #debugging
