Since the default all-users install location is now Program Files and thus not world-writable and with the advent of optimization-tagged .pyc files, the 'precompile' option in the installer should also precompile with -O and -OO. | |||

Doesn't it? It's supposed to... | |||

It doesn't appear to; my 'C:\Program Files\Python 3.5\Lib\__pycache__' is full of .pyc's, but none with an optimization tag. To confirm with math rather than eyesight, according to 'dir' there are 168 files in Lib\, and 168 in Lib\__pycache__ rather than the expected 168*3. For the record, I have not run this Python as a privileged user, so the contents of __pycache__ are not incidental; they were definitely created by the precompile option. | |||

Right, it's just doing the single pass. You're proposing making a slow part of the install three times slower, correct? Just to confirm :) | |||

Steve Dower added the comment: > You're proposing making a slow part of the install three times slower, correct? Just to confirm :) Indeed I am :). Or extend the precompile options to let the user do whatever of the three they want. The precompile option is meant as a startup time optimization. -O and -OO are meant as (very slim) runtime optimizations; it only makes sense that people actually concerned enough to use -O/-OO would rather have their startup time optimized as well. This is pretty low priority, though. | |||
