I've spun up a local kubernetes cluster containing a django app run via a pex file. Startup times are close to 15 minutes. I've set execution_mode to

venv

which seems to have reduced times to 5 minutes. Not using pex files (just python manage.py ...) seems to reduce startup times to around 30 seconds. Does anyone have any tips on making things faster with pex files? I rather stick with pex files as local development is leveraging them.

That blog post is good for solving pex-in-docker. As a meta point, if you set

PEX_VERBOSE=1

environment variable (or higher numbers) you can get a sense of where time is being spent, which may or not help optimise.

Interesting, there's definitely stuff happening. I see a bunch of: 1.

Laying out Spread PEX directory

, followed by a bunch of 2.

Installing zipped wheel install

, then a bunch of 3.

Executing installed PEX for
