I am doing some experimentation with discriminants and want to run a lot of perf-runs without bothering people in a PR.
Problem is that I get wildly different results for running on my machine vs running on https://perf.rust-lang.org/
I have a
Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz, nothing unusual.
My results are of low variance between runs on my local machine.
Basically my workflow is:
./x.py build --stage2
./target/release/collector bench_local ~/git/rust/build/x86_64-unknown-linux-gnu/stage2/bin/rustc <COMMIT_HASH>
The results are different enough that they are worthless for making any changes. Any idea?
