tracking issue for monitoring compiler performance

[nikomatsakis]

This is a tracking issue for the generic topic of monitoring compiler performance. We now have the perf.rust-lang.org infrastructure, but there are a number of extensions that would be helpful:

• Evaluate and improve the compile-time benchmark suite
  • The current suite was chosen somewhat haphazardly.
  • Some thoughts in this internals thread..
• Tracking the runtime of generated code.
  • The current test suite tracks only compilation time.
  • Create a benchmark suite for uncovering runtime regressions #31265: A rather preliminary effort to create a runtime benchmark suite.
• Improving the web interface: see the rustc-perf issue tracker.

Triage: I'm not aware of what's going on here. @nikomatsakis is this metabug still useful?

[pnkfelix]

I think we may be picking up this task soon. I’d leave the metabug open at least until the next Rust all hands?

I'm going to go ahead and close this metabug, I think the general shape should be tracked in issues on rustc-perf these days (and each of these has a dedicated issue there or is too broad for effective tracking).
