"Do you want a fast website, or do you want a feature-rich website?"
This is a false choice. The real question is: do you want a well-engineered website.
With proper architecture, lazy loading, code splitting, and performance optimization, you can have both speed AND rich functionality. The tradeoff only exists when you cut corners.
- Conversion: Every 100ms of latency costs 1% of conversions
- SEO: Core Web Vitals are now ranking factors
- UX: Perceived performance affects user trust
Here's what a high-performance build looks like:
- Image optimization: WebP/AVIF with responsive sizing
- Code splitting: Only load what's needed for the current view
- Edge caching: CDN for static assets, edge functions for dynamic content
- Font loading: Subset fonts, font-display: swap
- Third-party scripts: Defer non-critical scripts, self-host when possible
Don't optimize blindly. Focus on:
- LCP (Largest Contentful Paint): < 2.5s
- FID (First Input Delay): < 100ms
- CLS (Cumulative Layout Shift): < 0.1
Use real user monitoring, not just synthetic tests. Lab data and field data tell different stories.
Speed isn't a feature — it's a requirement. Don't let anyone tell you it's a tradeoff.
