## Summary
It took me a while to figure out why the benchmarks are extremelly flaky
(and slow) on my machine.
I documented my finding in the benchmarks.md file in case someone else
runs into the same problems as I
First, replace all usages in files in-place. I used my editor for this.
If someone wants to add a one-liner that'd be fun.
Then, update directory and file names:
```
# Run twice for nested directories
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
# Update files
find . -type f -print0 | xargs -0 rename s/puffin/uv/g
```
Then add all the files again
```
# Add all the files again
git add crates
git add python/uv
# This one needs a force-add
git add -f crates/uv-trampoline
```
The labels were missing when I generated the charts on my Arch machine.
Inspecting the intermediate SVG showed that we use Google's Roboto font
(and the rendering library doesn't support fallback fonts).
I installed the font and TADA, the labels appeared. I extended our
documentation to mention the required fonts.
Update the Benchmark documentation to explicitly document that it
requires Python 3.12.0 to run the non puffin benchmarks:
```
Benchmark 2: poetry (resolve-warm)
Current Python version (3.12.1) is not allowed by the project (3.12).
Please change python executable via the "env use" command.
Error: Command terminated with non-zero exit code: 1. Use the '-i'/'--ignore-failure' option if you want to ignore this. Alternatively, use the '--show-output' option to debug what went wrong.
```
I originally used Python 3.10, since 3.10 and 3.11 are by far the most
common (at least for [Ruff](https://pypistats.org/packages/ruff)). But
3.12 should give Python tools the most favorable benchmarks.
