Performance isn't vanity — it's conversion. Every 100ms improvement in load time increases revenue 1-2% for e-commerce. For a site doing $10M annually, a migration that cuts load time by 2 seconds is worth $200,000-$400,000 in additional revenue per year.
Cost

Developer satisfaction (State of JS)
Source: State of JS 2025 survey (stateofjs.com). Astro satisfaction ~84%, WordPress not directly surveyed in State of JS.
Teams on modern frameworks ship faster, iterate more, and retain talent longer. The framework choice affects every sprint, every quarter, every year.
Security
95%+
Attack surface reduction
Architectural analysis. Source: static sites have no server-side execution by design. Not a measured percentage.
Near zero
Security incidents post-migration
Organizations that migrated from WordPress to static frameworks report virtually no CMS-related security incidents.
The Payback Period
A typical WordPress-to-Astro migration for a mid-size content site costs $15,000-$40,000. Based on the cost savings, performance revenue lift, and security risk reduction, the payback period is 3-8 months. After that, every month is pure gain.
This isn't theoretical. These are the numbers organizations report after migration. The ROI case for modern infrastructure is the easiest business case most CTOs will ever make.
