rust-lang/rust CI timing tracking

This repository downloads CI timing data for each builder on rust-lang/rust's auto builds, based on the CPU usage data collection run in the background on rust's CI, and graphs it.

To use, run:

cargo run --release # May take a while on the first run, incremental
python3 walltime.py

You can edit walltime.py to adjust which builders are shown (see the filter_display function).
