[issue16908] Enhancing performance and memory usage

[Georg Brandl]

Georg Brandl added the comment:

The "performance" you're measuring here is mostly startup, i.e. loading all necessary modules.  On Python 3, there is more to load, e.g. the filesystem encoding, therefore startup takes a little longer.

There are efforts to improve startup time, see e.g. #16101.

The memory consumption is expected, again due to more modules loaded.  You cannot make any statement about the memory usage of a real-world application by just measuring the overhead of the interpreter.

The memory usage due to strings should be very similar to Python 2 starting with Python 3.3, due to PEP 393.

resolution:  -> works for me
status: open -> closed
superseder:  -> Verify all imported modules at startup are needed
