Perceived Speed Matters

Users judge speed by how quickly they can interact. Small wins like skeleton screens and prioritized content delivery often outperform big rewrites.

Low-Hanging Wins

• Defer non-critical JavaScript
• Use critical CSS
• Optimize images and use modern formats
• Cache aggressively at the edge

These changes usually yield immediate improvements.

Measure and Repeat

Profiling tools reveal hotspots. Fix the largest issues first and iterate in small, measurable steps.

Closing

Performance is continuous work. Make it part of your PR checklist and ship improvements incrementally.
