I just launched my portfolio at https://www.webdevcompass.com/ and spent weeks obsessing over performance.

The results so far:

✅ Desktop: A flawless 100/100.

⚠️ Mobile: Stuck around 95.

I’m using React + TypeScript + Vite. To get these scores, I’ve already implemented:

Image preloading for LCP.

Lazy loading for all non-critical components.

Delayed rendering for heavy decorative elements.

The big question:

Is that final 5% on mobile even possible with a Client-Side Rendered (CSR) React app, or do mobile CPU limitations make it a lost cause?

I’d love to hear your best "secret" tips for squeezing every last millisecond out of mobile browsers. What am I missing? 🛠️
