Warming a Multilingual Static Fleet at the Edge: Throughput, Origin Load, and Fail-Closed Abort Rules

Jermaine Harris · publication · 2026-09-20

Operational measurement of Cloudflare cache warming for the Animal Start multilingual static fleet. A 2026-08-14 16-cell burst matrix reached about 3.1k aggregate rps with origin load under 4, but sustained policy stays near 800 rps because hotter 800x4 cells fail-closed with NONE/429/BYPASS. A 2026-09-20 probe was not mixed into that matrix. No production --apply in this writing campaign.

Moving WordPress Plugin Compute to Rust FFI: An Experience Report on Sitemaps, Related Posts, and Redirects

Jermaine Harris · publication · 2026-09-20

Experience report timing three WordPress plugin kernels (XML sitemaps, related-posts scoring, and redirect lookup) as PHP fallbacks, PHP FFI into Rust cdylibs, and native Rust. On an i5-12600KF, sitemap FFI loses to PHP because of JSON marshalling; related-posts PHP is faster because it uses a weaker ranker; a redirect radix trie is about 700x faster than a linear PHP scan. Production WordPress was not cut over. Expanded A4 technical report with stdev tables and FFI architecture notes.
