Eliminate Forced Reflow Issues
Medium Impact+5 points estimated
Why It Matters
Forced reflows cause 65.9ms of wasted computation time, blocking the main thread and potentially affecting INP.
How to Fix
Audit JavaScript code for DOM queries after style changes. Batch DOM reads and writes separately to avoid layout thrashing. Use CSS transforms instead of changing geometric properties like width/height when possible.

What This Score Means
A score of 100 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 achieves a perfect performance score of 100/100, indicating excellent overall speed and user experience. However, there are still some optimization opportunities that could improve repeat visitor performance and reduce minor rendering inefficiencies. The most significant issue is render-blocking CSS that's delaying initial page rendering by about 110ms, which could be fixed by deferring or inlining the stylesheet. Additionally, implementing proper browser caching for static assets could save 10KB on repeat visits, and addressing forced reflows in JavaScript could eliminate small performance hiccups during page interactions.
Other Optimization Recommendations
Fix Render Blocking CSS
High Impact+8 points estimatedWhy It Matters:
The blocking CSS file delays both FCP and LCP by 100ms each, directly impacting Core Web Vitals.
How to Fix:
Inline the critical CSS from cf.errors.css directly in the HTML head. Defer the remaining CSS using media='print' onload='this.media="all"' attribute. Consider removing Cloudflare error page assets if they're loading unnecessarily on the main page.
Implement Efficient Resource Caching
Low Impact+2 points estimatedWhy It Matters:
Zero cache lifetime on static assets wastes 10KB on repeat visits and slows down returning users.
How to Fix:
Configure your web server to set Cache-Control headers with max-age=31536000 for static assets. Add versioning to CSS and image URLs for cache busting when needed. Set appropriate cache headers for cf.errors.css and image assets.
