[issue33500] Python TKinter for Mac on latest 2.7.15 still extremely slow vs Windows
New submission from Michael Romero : Hello, I have recently been working with a PAC-MAN project developed by Berkeley for their A.I. course. My primary workstation is a Touchbar MBP (3.1ghz core i7 w/16gb RAM and an SSD). I had noticed how PAC-MAN's performance would sort of... stutter, when running on my Mac, while performing incredibly quick on a nearby gaming computer. I had previously believed it to be due to the differences in specs between systems. This is not the case, however, as the performance of PAC-MAN is extremely quick even within a VM ran via Parallels on the same Macbook whose native python performance was extremely sluggish. I have seen recent issues submitted here and supposedly resolved that are intended to address a performance issue with Tkinter and Mac OS/X. While the underlying issue mentioned in those particular tickets may have been addressed, the overall performance difference between Mac and Windows (and perhaps others) with Tkinter on Mac has not been. The following URL includes the PAC-MAN implementation I'm referring to: http://ai.berkeley.edu/project_log.html The link above contains another link to download the "multiagent.zip". https://s3-us-west-2.amazonaws.com/cs188websitecontent/projects/release/multiagent/v1/002/multiagent.zip After extraction, running "python pacman.py" with a system running the most recent 2.7.15 64bit release (on a fully patched OS/X) will allow you to see the sluggish performance of PAC-MAN I'm describing when compared to the same exact codebase running on a Windows system (and perhaps linux, though I have not yet tried to run it there), on a Windows VM living on the same system. -- components: Tkinter messages: 316520 nosy: Michael Romero priority: normal severity: normal status: open title: Python TKinter for Mac on latest 2.7.15 still extremely slow vs Windows versions: Python 2.7 ___ Python tracker <https://bugs.python.org/issue33500> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Michael Romero added the comment: "search.zip" on http://ai.berkeley.edu/project_log.html will also display the same performance issue. -- Added file: https://bugs.python.org/file47587/search.zip ___ Python tracker <https://bugs.python.org/issue33500> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Michael Romero added the comment: I don't have a minimal failing example as is being requested. What I do have is the smallest version of the code published by Berkeley's AI course that I could find that allows easy demonstration of the issue. "python pacman.py" is enough to demonstrate the latency difference between the MacOS and Windows versions of Python. The specific calls causing the program to run slowly on MacOS I leave to this team to determine / resolve. -- ___ Python tracker <https://bugs.python.org/issue33500> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Michael Romero added the comment: * What version of macOS are you using? "Is fully patched" the latest High Sierra? - I've tried the version bundled with MacOS fully patched high sierra, as well as versions downloaded from python.org, Intel, and ActiveState. They all demonstrate the slowness. * Which variant of the Python 2.7.15 installer did you use? - I used the 64-bit only installer from python.org during one test. However, all versions I've tried on MacOS seem to demonstrate the issue. * Did you install ActiveState Tcl/Tk (check if there is a Tk.framework in /Library/Frameworks)? If so, which version? - I used the bundled version of ActiveState Tcl/Tk that came with the 64-bit only installer. I have also experimented with alternate versions of python that use a Tcl/Tk externally. "8.5" is the version I see on my system now. -- ___ Python tracker <https://bugs.python.org/issue33500> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
