CI Ruby 3.3 Rails 8 MIT In development

A benchmarking dataset for Linux distros: Phoronix Test Suite runs on Ubuntu, Fedora, and Debian, captured monthly in GitHub Actions on both x86 (GitHub-hosted runners) and arm64 (an Oracle Ampere VM), with this Rails dashboard and R parsers consuming the same composite XML.

Note fresh captures land in the repo on the 1st of every month via the capture-benchmarks workflow. This dashboard reads the same composite XML the R parsers do. See the README setup section to run it locally.

Sample results: Ubuntu 26.04 LTS

The fully parsed sample runs on AMD EPYC 9V74 80-Core (2 Cores / 4 Threads), 16GB RAM, 2 x 81GB Virtual Disk, via Docker. Each benchmark ran 3 to 8 times depending on the test; the dot shows the mean, the band shows ±1σ around it.

How the pieces fit

The R parsers and this Rails app are interchangeable consumers of the same pts/composite.xml: run the static analysis with R alone, or use the dashboard alone, or both.

Project status

DONE Phoronix sample for Ubuntu, Fedora, Debian, parsed into per-distro writeups
DONE benchmarks/generate_writeup.rb turns a captured composite.xml into the per-distro markdown writeups this showcase parses
DONE Monthly CI capture in .github/workflows/capture-benchmarks.yml across ubuntu/fedora/debian on x86, plus arm64 parity for all three on a real Oracle Ampere VM
DONE Capture and publish split into separate jobs so the x86 matrix runs fully in parallel with no git-push races
DONE This showcase folded into the Rails dashboard at /showcase, retiring the standalone Next.js site
WIP Rails dashboard's own user-submitted benchmark CRUD (separate from this showcase)
DONE arm64 captures rendered on the per-distro pages behind an x86/arm64 switch
TODO Wire generate_writeup.rb into the monthly capture workflow so writeups refresh automatically instead of by hand
TODO Cross-distro comparison page
TODO Fill in Kamal deploy targets and ship the dashboard
