Beamline startup timing diagnosis tools #34

Open ZLLentz opened 4 years ago

ZLLentz commented 4 years ago

Feature Request

Provide easy ways to diagnose which files/function calls contribute to the slowdown of python session startup/running
e.g. hutch-python --profile startup

Existing Alternatives

Flounder a bit, pick your favorite profiler, outfit debug libs with timing checks

Context

Hutch python startup is pretty slow right now

ZLLentz commented 4 years ago

I want to re-use some of the tools we employed in typhos and distribute them to other libraries.

A first-pass simple but (maybe?) useful metric would be timing safe_load blocks.

Also, related: loading speed has also drastically improved with @ZLLentz's environment deployment to local machines' hard drives.

ZLLentz commented 4 years ago

I like the idea of timing safe_load blocks, that will help us zero in on which parts of the load are particularly slow

ZLLentz commented 4 years ago

I like it so much and it's so easy to do I'm going to implement it really quickly
