From 59ef6467f96387dbb0b6e20a78f8300f552257a4 Mon Sep 17 00:00:00 2001 From: Lonnie Ezell Date: Fri, 23 Oct 2026 16:24:45 +0200 Subject: [PATCH 1/3] perf(#10617): skip redundant work in `RouteCollection::create()` MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Run the placeholder `str_ireplace` loop only when the route key contains `:`, and call `helper('array')` only on the first `create()` per collection. The route table output is unchanged. Route table build, PHP 8.3, OPcache on, median of 7 runs: 100 routes 203 -> 168 µs, 1000 routes 2044 -> 1680 µs (~18%).
