Remove Legacy JavaScript Polyfills

High Impact+15 points estimated

Why It Matters

Unnecessary polyfills waste 53 KiB and delay LCP by 200ms for modern browsers that don't need them.

How to Fix

Update your Babel configuration to exclude polyfills for ES6+ features like Array.from, Object.assign, and Promise methods. Set browserslist to exclude Internet Explorer and target only modern browsers. Remove @babel/plugin-transform-regenerator and other legacy transforms from your build pipeline.

What This Score Means

A score of 27 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 casino website has severe performance issues with a critically low score of 27/100. The biggest problem is an enormous 965 KiB of unused JavaScript code that's blocking page rendering for nearly 5 seconds, causing your Largest Contentful Paint to crawl at 18.9 seconds - far beyond acceptable limits. The site is loading massive JavaScript bundles from multiple sources (including a 750 KiB main bundle that's 68% unused) while also suffering from render-blocking CSS files that delay initial content by almost 6 seconds. Immediately removing unused JavaScript, implementing code splitting, and deferring non-critical resources could dramatically improve your Core Web Vitals and user experience, potentially boosting your performance score by 40+ points.

Other Optimization Recommendations

Eliminate Render-Blocking CSS Resources

High Impact+25 points estimated

Why It Matters:

CSS files block initial render for 5.97 seconds, severely delaying both FCP and LCP metrics.

How to Fix:

Inline critical CSS for above-the-fold content directly in the HTML head. Defer non-critical CSS using media='print' onload='this.media="all"' technique. Split your bundle.css into critical and non-critical parts, loading only essential styles synchronously.

Reduce Unused JavaScript Code

High Impact+20 points estimated

Why It Matters:

965 KiB of unused JavaScript increases bundle size and execution time, blocking user interactions.

How to Fix:

Enable tree-shaking in your webpack configuration to eliminate dead code. Split the 750KB bundle.js into smaller chunks using dynamic imports. Remove unused features from communication-widgets.caliente.mx bundle and defer loading until needed.
