  • Limit comparison page data retrieval and cache what is retrieved. At page load, hide most of the unchecked executable groups
  • Replace jqplot with chart.js 4.4.4 and dygraphs.
  • Add errorbars using the std data from the benchmarks to the timeline plots

The net effect is to make the comparison page much lighter. The current version is very heavy on my browser. It also adds some color and better rendering to the various graphs.

I tested this locally with a data dump from 2 years ago.

AI disclosure: claude code helped me with the coding, I came up with ideas and verified the changes. I take full responsibility for this PR.

Sorry, something went wrong.

Uh oh!
