Reduce Turbo JavaScript Overhead
High Impact+8 points estimated
Why It Matters
85% of Turbo JavaScript is unused and causes 62ms of forced reflows, impacting user interactions.
How to Fix
Configure Turbo to only load required modules using import maps in Rails 7. Add data-turbo='false' to pages that don't need SPA behavior. Optimize DOM queries in turbo:load events to avoid layout thrashing.

AI Performance Analysis
This Ruby on Rails site has good performance with a score of 86/100, but there's room for improvement in loading speed. The biggest issue is render-blocking Google Fonts requests that are delaying both First Contentful Paint and Largest Contentful Paint by 1.3 seconds, causing pages to take 3+ seconds to show meaningful content. Additionally, the site is loading 25KB of unused JavaScript from Turbo and ActionCable libraries, and experiencing forced reflows that create layout stuttering. To boost performance, prioritize deferring or inlining the Google Fonts, remove unused JavaScript code, and optimize the font loading strategy to achieve faster page rendering.
Other Optimization Recommendations
Optimize Font Loading Strategy
High Impact+12 points estimatedWhy It Matters:
Render-blocking Google Fonts are delaying LCP and FCP by 1.3 seconds.
How to Fix:
Add <%= preload_link_tag 'https://fonts.googleapis.com/css2?family=Bricolage+Grotesque...', as: :style, crossorigin: 'anonymous' %> to your Rails layout. Use font-display: swap in CSS and consider self-hosting fonts with the google_fonts gem for better performance.
Improve Cloudflare Cache Configuration
Medium Impact+3 points estimatedWhy It Matters:
Short cache lifetime on static assets forces unnecessary re-downloads on repeat visits.
How to Fix:
Update your Cloudflare page rules to set longer cache TTL for static assets. Configure Rails asset pipeline with config.public_file_server.headers for far-future expires headers. Set email-decode.min.js to cache for at least 30 days.
