Reduce Unused JavaScript Bundle
Medium Impact+6 points estimated
Why It Matters
45% of JavaScript (20KB) in main bundle is unused, increasing parse time and delaying FCP by 150ms.
How to Fix
Configure SvelteKit's code splitting to defer non-critical chunks. Use dynamic imports for features not needed on initial page load. Run bundle analyzer to identify and remove dead code from the Bsq8Px5l.js chunk.

What This Score Means
A score of 83 falls in the "Needs Improvement" 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 gaming tracker website has decent performance with a score of 83/100, but there are several opportunities for improvement. The biggest issue is forced reflows in JavaScript that are causing layout thrashing and contributing to a poor First Input Delay of 230ms, which could make the site feel unresponsive to user interactions. Additionally, the site is serving oversized images that are 31KB larger than necessary and has 20KB of unused JavaScript that's slowing down the initial page load. Optimizing image sizes, fixing the JavaScript layout issues, and removing unused code could push this site into the 90+ performance range and deliver a noticeably smoother user experience.
Other Optimization Recommendations
Optimize Image Responsive Sizing
High Impact+8 points estimatedWhy It Matters:
Images are 27% larger than needed for display dimensions, directly delaying LCP by 200ms.
How to Fix:
Generate multiple WebP sizes (200w, 300w, 400w) for game covers. Update srcset to match actual display dimensions (315x472) instead of serving 400x600 images. Use CSS object-fit: cover to maintain aspect ratios while serving appropriately sized images.
Eliminate Forced Reflow Operations
High Impact+12 points estimatedWhy It Matters:
JavaScript is causing 113ms of forced reflows that block the main thread and increase potential input delay.
How to Fix:
Cache DOM measurements before making style changes in your SvelteKit components. Batch DOM reads and writes separately using requestAnimationFrame. Replace direct offsetWidth/offsetHeight queries with ResizeObserver API for dynamic layout calculations.
