JCH Optimize, by Samuel Marshall - Joomla Extension Directory

Introduction

Site Performance, Core Enhancements, SEO & Metadata, Performance, Site speed

JCH Optimize improves the performance of your website by performing several optimizations to the HTML page aimed at improving the Web Vitals measured by PageSpeed Insights, such as First Contentful Paint (FCP), Largest Contentful Paint (LCP), Speed Index (SI), Cumulative Layout Shift (CLS), Time to Interactive (TTI), and Total Blocking Time (TBT). These metrics attempt to quantify the quality of the user experience. JCH Optimize can improve these metrics to provide a better user experience and improve your PageSpeed scores.


Optimizations Performed By JCH Optimize

JCH Optimize optimizes your pages by automatically performing some recommended strategies offered by PageSpeed, which include:

  • Minify CSS and JavaScript files and the HTML. Unnecessary whitespaces and other characters are removed to reduce network payload sizes and script parse times.
  • Eliminate Render-Blocking Resources. Inline critical JavaScript and CSS and defer all non-critical resources to prevent resources from blocking the first paint of your page.
  • Defer offscreen images. Offscreen and hidden images are lazy-loaded after all critical resources have finished loading to lower Time To Interactive (TTI).
  • Add Width and Height attributes to images. Set an explicit width and height on image elements to reduce layout shifts and improve CLS.
  • Enable text compression. Boilerplate codes are placed in the .htaccess files at the site's directory root to instruct the server to serve text-based resources with compression (deflate or brotli) to minimize total network bytes.
  • Preload critical resources. Automatically analyzes each page to identify critical resources to load with a high priority by HTTP/2 enabled servers to improve LCP time.
  • Reduce initial server response. A Page Cache plugin is included in the package that integrates well with the JCH Optimize component and significantly reduces time-to-first-byte.

… and more.

Benefits of Using JCH Optimize

Research has confirmed that 40% of visitors will leave a website if it takes more than 4 seconds to download. Also, Google and other search engines have indicated that their ranking algorithm increasingly factors website download speed. The benefits of using JCH Optimize then include the following:

  • Improved user experience. Your users will have a pleasant experience as they browse your site.
  • Improved SEO. Your rankings in Google search pages can increase and improve organic visibility in internet searches.
  • Improved conversions. Your website revenue also increases with increased traffic volume and visitor retention.

This plugin is the best around in my opinion I have tried the rest including Jfinalizer and found they broke the CSS of my site and other functions.



This plugin however functions flawlessly and has significantly reduced my site load speed.



Recommended addition to all joomla sites

WOW !!

This extensions it rock and excellent, its make my site load and running faster.

Keep work guys
I would have to give props to the developer - What a well written plugin.



I run a 4x4 site - and have been looking ways to compress the css. The template currently has like 10 files it loads every page.



I am not big on giving reviews but man this one blew away any competition. I have tried RokZipper - it works to an extent - CSS Compress does ok - but nothing compares to this. Highly Recommend.



WHAT I WAS RUNNING AT -



Global Statistics



Total HTTP Requests: 35

Total Size: 2093087 bytes



AFTER ENABLING THIS PLUGIN



Global Statistics



Total HTTP Requests: 15

Total Size: 1940928 bytes

works perfectly

Had problems to merge several js and css, tried other available tools but they all failed.

This one did the job with the default parameters!



Thank you very much!
