Closes #14902

Does this PR introduce a user-facing change?

None

[eriksjolund]

I wrote a very sketchy draft.
Currently it's very far from being finished.

The bane of my existence, trailing white spaces! Other than that, LGTM. You might consider having this published on the Enable Sysadmin website too, they'd probably be happy to have it.

[eriksjolund]

@TomSweeneyRedHat Whitespaces now removed. The document is more of a sketch right now.
I'm adding some ideas for how such a performance document could look like.

I copied in some old text from https://github.com/eriksjolund/using-podman-quick-instructions#example-fedora--speed-up-podman-build-by-reusing-the-dnf-metadata-cache without much thought. My plan was to clean this up a bit. I could take a look over the weekend.

[eriksjolund]

The document is still a work-in-progress. I'm still a bit clueless about what type of contents is meaningful to include. I would like to avoid adding information that should be better placed in a more specific document such as basic_networking.md or socket_activation.md.

A side-note: I moved some text out of this PR into
https://github.com/eriksjolund/podman/blob/performance.md_extra_text/docs/tutorials/performance_unused_text.md

The moved text was a mix of

• too obvious
• too general (building smaller containers)
• too much a special case (using :U volume flag)

A friendly reminder that this PR had no activity for 30 days.

@eriksjolund any update?

[eriksjolund]

Please suggest removal of text and sections that could be skipped.
I'm really not convinced that all of the text belong in such a document.

I remove the draft status of the PR.

[vrothberg]

@rhatdan are we good to go?

Apologies @eriksjolund, this one fell under the radar.

[eriksjolund]

@vrothberg no worries. Feel free to merge, if you think the text makes sense. Also feel free to close the PR or make major additions/changes/deletions. I don't mind if you make major changes as I believe the document could be improved a lot with input from others.
