Optimize HTMX Library Usage
Medium Impact+2 points estimated
Why It Matters
HTMX is triggering layout recalculations that could delay user interactions and hurt INP scores.
How to Fix
Review HTMX configurations to minimize DOM queries during dynamic content loading. Use CSS transforms instead of changing layout properties for animations. Consider lazy-loading HTMX for non-critical interactive elements.

What This Score Means
A score of 98 falls in the "Good" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.
This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.
Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis
This website performs exceptionally well overall with a score of 98/100, but has one notable issue affecting user experience. The biggest problem is forced reflows caused by JavaScript code that's making the browser recalculate page layouts unnecessarily, particularly in the frontpage.js file which is consuming 36.7 milliseconds of processing time. While the Speed Index of 3.8 seconds is decent, the forced reflows are likely contributing to visual delays as content loads. Optimizing the JavaScript code to avoid querying element dimensions after DOM changes could eliminate these performance hiccups and make the already fast site feel even more responsive to users.
Other Optimization Recommendations
Eliminate Forced JavaScript Reflows
High Impact+5 points estimatedWhy It Matters:
Forced reflows from frontpage.js and htmx cause 37.8ms of blocking main thread time, directly impacting INP and Speed Index.
How to Fix:
Move DOM geometric queries (offsetWidth, scrollTop) outside the render loop in frontpage.js. Batch DOM reads before DOM writes to avoid layout thrashing. Cache element dimensions instead of repeatedly querying them during animations or interactions.
Optimize Speed Index Performance
Medium Impact+3 points estimatedWhy It Matters:
Speed Index of 3.8s indicates slow visual content population, affecting user perceived performance despite good overall score.
How to Fix:
Prioritize above-the-fold content rendering by inlining critical CSS. Preload key resources like fonts and hero images using <link rel='preload'>. Defer non-critical JavaScript execution until after initial paint completion.
