> we did was analyze what happens when Podman starts a container and why it takes so long. It turns out there was a lot of low-hanging fruit.

I've done this analysis for lots of software before, Windows has a really nice tool called Process Monitor that I've used to find huge slow downs before. Point it at a process and it'll tell you the every bit of IO that the application does, and at that point you can just start digging and opening bugs.

IMHO almost every piece of software of any significant size horribly misbehaves. Opening the same file again and again, writing out lots of tiny temp files, reading the same key from the registry (or some config file) over and over again , and worst of all, using fixed timeouts waiting for a task to complete instead of doing the work to make things properly event based.

On that last note, timeouts instead of event callbacks (or some sort of signaling system) is the cause of so much slowness across our entire industry. If something you are doing on a computer takes a human noticable amount of time, and you aren't throwing around tens of GBs of data or waiting on a slow network, then you are flat out doing something wrong.
