Re: making executables smaller

[Daniel Bradburn]

A couple of things you can try:

* Generate a directory rather than onefile, on the directory you can apply du
-hs * | sort -h -r (or treesize if you are using windows
https://www.jam-software.com/treesize_free) to see which folders / files
are taking up a lot of space. Then once you see what is taking up a lot of
space you can try and figure out why it is being included, maybe you have a
load of unused imports? With pyinstaller you can explicitly exclude modules
you know you won't need with --exclude-module once you've optimised the
directory build you can of course switch back to onefile

* If all else fails you can use upx to compress your binary files (dlls +
exe) which can help reduce the overall size:
https://pythonhosted.org/PyInstaller/usage.html#using-upx

Hope this helps.

Re: gevent

Hi Larry,

I'm afraid I don't have any experience using gevent with wsgi, perhaps you
could try posting directly on the Google group
