Eliminate Page Redirects
High Impact+12 points estimated
Why It Matters
A redirect from turczynski.com to www.turczynski.com wastes 780ms and delays both LCP and FCP by 800ms each.
How to Fix
Configure your DNS/hosting provider to serve content directly from the canonical URL (www.turczynski.com). Update all internal links to point directly to the www version. Set up a 301 redirect at the server level if the non-www version must redirect.

AI Performance Analysis
This website has good performance with a score of 80/100, but there are some significant opportunities for improvement. The biggest issue is a redirect from the non-www to www version of the site, which wastes 780ms and delays both First Contentful Paint (3.2s) and Largest Contentful Paint (4.1s). Removing this redirect and reducing unused JavaScript (which could save 81KB and 450ms) would have the most immediate impact on loading speed. Additionally, optimizing server response time and improving image compression could further enhance the user experience and push the performance score into the excellent range.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+8 points estimatedWhy It Matters:
81KB of unused JavaScript delays LCP by 450ms and wastes bandwidth on every page load.
How to Fix:
Audit your React and markdown processing bundles to identify unused code. Use tree-shaking to eliminate dead code from markdown-jpoeBJsD.js (71% unused) and react-Bd5gNP4v.js (51% unused). Consider code-splitting to load JavaScript modules only when needed. Use dynamic imports for non-critical functionality.
Optimize Server Response Time
Medium Impact+4 points estimatedWhy It Matters:
Slow document request latency adds 60ms to both LCP and FCP, impacting perceived performance.
How to Fix:
Enable gzip/brotli compression on your server for HTML responses. Optimize your server configuration to reduce Time to First Byte (TTFB). Consider using a CDN to serve content closer to users. Review server-side processing to eliminate unnecessary delays.
