Features & Specs

  1. Performance

    PyPy is known for its superior execution speed and performance, often outperforming the standard CPython interpreter for many workloads thanks to its Just-in-Time (JIT) compilation strategy.

  2. Compatibility

    PyPy aims to be compatible with standard Python, so many programs and libraries that run on CPython should work on PyPy without or with minimal changes.

  3. Memory Efficiency

    Due to its garbage collection mechanism, PyPy often results in lower memory usage as compared to CPython, which can be beneficial for memory-intensive applications.

  4. Concurrency

    PyPy provides better support for concurrency, including potentially avoiding some of the Global Interpreter Lock (GIL) performance issues present in CPython.

  • Pydrofoil: Accelerating Sail-based instruction set simulators
    Gains than using either compiler alone. This uses the PyPy JIT framework to speed up a RISC-V simulator. https://pypy.org/ https://github.com/pydrofoil/pydrofoil Pydrofoil: A fast RISC-V emulator generated from the Sail model, using PyPy's JIT. - Source: Hacker News / 11 days ago
  • One Billion Nested Loop Iterations
    "On average, PyPy is 4.4 times faster than CPython 3.7." https://pypy.org/. - Source: Hacker News / 5 months ago
  • Ask HN: Are my HPC professors right? Is Python worthless compared to C?
    If you're going the pure Python route, don't forget to try PyPy[1], an alternative JITed implementation of the language. A seriously underrated project, IMHO. Most time it speeds up execution by a factor of 2x-4x, but improvements of about two orders of magnitude are not unheard of. See for example [2]. Numeric, long-running code shoud suit PyPy optimizations well. [1] https://pypy.org/ [2]... - Source: Hacker News / 6 months ago
  • Yes, Ruby is fast, but…
    Python: My Python-foo is limited, so I only ported the last problem (a simple while loop) and ran it with PyPy. It takes a bit less of time:. - Source: dev.to / 12 months ago
  • Python 3.12: A Game-Changer in Performance and Efficiency
    If you r looking for performance with almost fully supported C Extensions , pypy.org for you , 20x faster than cpython still. Source: about 2 years ago
  • What change should Python 4 bring, in your opinion?
    I think you never heard of PyPy it is drop in replacable python written in Python and It is jit avg 5x faster than Python , 20x faster in some cases. Https://pypy.org. Source: almost 3 years ago
  • 4x smaller, 50x faster
    Well, pypy is a thing. Of course, your overall point still stands. Source: over 3 years ago
  • Microsoft is hiring, looking to speed up cpython
    Why don't they just sponsor pypy.org ? Its already 4x faster in average , 20x in many cases. We are using in 4 of our projects with one of them 10k active concurrent connections max , and its absolutely amazing. Its a realtime telemedince/chatroom (OnDoctor check in playstore). And we host it on 40$ Digital ocean machine. A lot less memory usage and so much faster. Source: almost 4 years ago
