Have you considered any aggregate performance scores for rubybench? There are a couple interesting questions…
Which tests are most relevant, that is, which tests best reflect ruby performance under different circumstances (e.g. Rails web app, sinatra/rack web app, number crunching, etc)?
At a glance, how does a version of ruby compare to other versions of ruby. Is ruby getting faster? Is garbage collection less disruptive (or more)?
I see value in the specific tests, but as first time visitor or as a general ruby developer, it’s not obvious how a version of ruby compares to others, holistically.
Have you discussed aggregate metrics or a small set (1-3) of metrics that give viewers an at a glance view of performance?
