Fix Forced Layout Reflows
High Impact+20 points estimated
Why It Matters
JavaScript is causing 316ms of forced reflows that block the main thread and delay interactions.
How to Fix
Batch DOM reads and writes in your Rails view helpers to avoid layout thrashing. Cache geometric properties like offsetWidth instead of repeatedly querying them. Move style calculations to CSS using transforms instead of JavaScript positioning. Profile the chunks causing reflows (8001.js and 946.js) to identify specific DOM manipulation code.

What This Score Means
A score of 44 falls in the "Poor" 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 Ruby on Rails site has poor performance with a score of 44/100. The biggest problem is excessive unused JavaScript (391 KiB), particularly from Google Ads and cookie consent scripts, which is causing a painfully slow 12.4-second load time and blocking user interactions for over 770ms. The site is also loading 21 separate JavaScript chunks in a dependency chain that takes 443ms to complete, while serving unminified JavaScript files and oversized images. Removing unused JavaScript, minifying remaining scripts, and optimizing the image delivery could improve the score by 30+ points and dramatically reduce load times.
Other Optimization Recommendations
Eliminate Unused JavaScript Dependencies
High Impact+25 points estimatedWhy It Matters:
391 KiB of unused JavaScript delays LCP by 1.95 seconds and blocks user interactions.
How to Fix:
Configure Rails asset pipeline to code-split chunks more granularly using dynamic imports. Remove unused Google Ads and tracking scripts from critical rendering path. Use Rails' javascript_include_tag with defer attribute for non-essential scripts. Audit OneTrust cookie consent library for unused features.
Optimize Image Delivery Strategy
Medium Impact+8 points estimatedWhy It Matters:
Images are oversized by 161 KiB and could improve perceived load performance.
How to Fix:
Use Rails' image_tag with srcset attribute to serve responsive images at correct dimensions. Compress PNG images using ImageOptim or similar tools in your asset pipeline. Convert large images to WebP format with Rails Active Storage variants. Set proper width/height attributes to prevent layout shifts.
