Common Speed Killers: What’s Really Slowing You Down
Before we dive into solutions, let’s identify the most common performance bottlenecks we see in modern websites:
1. Server Response Time Issues
Slow hosting providers
Inefficient database queries
Lack of proper caching
Server-side rendering overhead
2. JavaScript Bloat

The Static Site Revolution: A Game-Changing Approach
Here’s where it gets exciting:
Static site generation is revolutionizing how we build high-performance websites. But what exactly is it?
What Are Static Sites?
Static sites are pre-built at deploy time, meaning every page is generated ahead of time rather than on each user request.
This approach offers several significant advantages:
Lightning-fast load times
Improved security
Lower hosting costs
Better reliability
Superior SEO performance
