Combined with HostingStep's independent benchmarks showing managed WP TTFB of 365-470ms (vs Cloudflare ~45-50ms), the gap is real but small.\n\n**Confidence:** Directional. No public head-to-head matched-content benchmark exists; this is a triangulation from multiple agency case studies.\n\n**Practical implication:** **don't recommend a migration on CWV grounds alone if the existing WordPress site is already on managed hosting and uses Gutenberg.** Migration only makes sense if there are *measured* INP issues, integration requirements WP can't serve, or editor-workflow improvements worth the migration cost.\n\n**Threshold to revisit:** if a head-to-head benchmark publishes showing the gap is >5 pp CWV pass rate at p75, downgrade the equivalence claim.","rationale_body":null,"metadata":null,"links":{"outgoing":[{"slug":"wppoland-elementor-to-gutenberg-40pct-speed","title":"WPPoland: Elementor → Gutenberg rebuilds yield ~40% mobile site speed increase (multi-client benchmark)","kind":"reference","scope":"business","link_type":"depends-on"},{"slug":"managed-wp-ttfb-hostingstep-2025","title":"Managed WordPress host TTFB benchmarks (HostingStep 2025, 34 hosts, 1,960+ days of 24/7 monitoring)","kind":"reference","scope":"business","link_type":"depends-on"}],"incoming":[{"slug":"wordpress-cwv-causal-attribution-2026","title":"WordPress CWV gap causal decomposition (May 2026): ~40-50% hosting/TTFB, ~20-30% page builders, ~15-20% plugins, ~5-10% core, ~5-10% theme","kind":"reference","scope":"business","link_type":"relates-to"}]},"created_at":"2026-05-22T21:24:18.390Z","updated_at":"2026-05-22T21:24:18.390Z"}
