Summary

  • Checked foundation.zurb.com (24.8s in the 500-page run, untouched by this round's live testing) directly rather than assume the font-face fix (round 168, PR engine: fetch a font-face slot's candidate rules concurrently, not one at a time #267) also explains it: still ~40s after that fix, but DisableJS=true drops it to ~6.2s on the same page — its slowness is JS-settle-related, not the font-face-slot bug round 168 fixed.
  • cs.cmu.edu itself could not be cleanly re-measured: a careful single re-check well after the fix merged still showed ~45s, consistent with this round's own earlier live testing having triggered the origin's own throttling, which outlasted the session rather than the fix being ineffective — the deterministic local test (already in PR engine: fetch a font-face slot's candidate rules concurrently, not one at a time #267) remains the real evidence for it.
  • Docs-only correction, no code change.

Checked foundation.zurb.com (24.8s in the 500-page run, untouched by
this round's live testing) directly rather than assume the font-face
fix (round 168, PR #267) also explains it: still ~40s after that fix,
but DisableJS=true drops it to ~6.2s on the same page -- its slowness
is JS-settle-related, not the font-face-slot bug round 168 fixed.

cs.cmu.edu itself could not be cleanly re-measured: a careful single
re-check well after the fix merged still showed ~45s, consistent with
this round's own earlier live testing having triggered the origin's
own throttling (escalating response times observed before the fix
even shipped), which outlasted the session rather than the fix being
ineffective -- the deterministic local test (already in PR #267)
remains the real evidence for it.
