Basic and advanced tips and tricks to optimize your Joomla website in order to achieve maximum performance - a presentation by Tenko Nikolov for JoomlaDay Chicago 2012.
It requires 50% more concentration when using badly performing website. Make it easier for your users, not harder… A faster website can help your website in many ways. The faster the website, the lower the bounce rate and the higher the conversions. This mean higher sales, ad revenue and ultimately money. Here are 10 ways you can speed up your website: Hosting Provider – Who is hosting your website and how are they hosting it? Utilize Caching – Page Cache, Database Cache, Object Cache, Browser Cache, Reverse Proxy Combine CSS and JS files – Load JS in the footer whenever possible Use a CDN -A Content Delivery Network (CDN) will ‘put a rocket behind your static content’ Reduce and Optimize Images – Use CSS3 whenever and wherever possible, save images for web Use Compression – Save bandwidth and speed up your website Use Sprites – Load JS in the footer whenever possible Monitor Your Website – CPU usage, Physical Memory, Average Load, Disk I/O utilization, Network I/O Optimize your Database Regularly – Optimizing database tables regularly will help improve website performance Mobile and Tablet Optimization – Use CSS3 Media Queries, JS and service-side technology to speed up devices
Good UX has always been one of the key factors for success in the contemporary web development and there fore has led to huge improvements in our industry in the last years. Nowadays the UX of a software product is not responsibility only of the UX Architects / Producers, but to each individual involved in the creation of an app or a website, including the Front-end developers. The talk presents a summarized list of DOs and DON’Ts, which Stoyan and his team believe should be respected by the Front-end developers if they want to build a useable web product, up to and above industry standards. There will be a lot of case studies and actual examples taken from Despark’s experience in the field.
Web performance optimization can be done at three levels - general, server-side, and technology. At the general level, techniques include minimizing HTTP requests, optimizing images, minifying files, avoiding redirects and empty sources. Server-side optimizations involve techniques like content delivery networks, cookie-free domains, caching, and gzip compression. At the technology level for dynamic sites like Joomla, optimizations include flushing buffers early and optimizing database queries. Performance can be measured using various online tools.
Agile is taking over as the proffered methodology for development. Here are the key advantages of Agile software development.
JavaScript is a client-side scripting language that allows for more web functionality on the user's machine, improving server performance and page load times. jQuery is a popular JavaScript library that simplifies tasks like HTML document manipulation, event handling, and Ajax calls. To use jQuery, include the jQuery script in an HTML file and use jQuery syntax with $ selectors to target elements and perform actions on them. Callbacks allow functions to execute asynchronously after their parent functions complete.
My improved presentation on how to speed up Wordpress and optimize it's performance. Also covers why we still need to care about page load time.
This document provides tips for optimizing a Joomla site for speed. It recommends keeping Joomla updated, choosing extensions wisely, simplifying templates, enabling compression, caching plugins and .htaccess rules. Specific extensions like JCH Optimize are suggested for combining and minifying CSS/JS and images. Server-level optimizations include using a CDN, opcode caching, moving PHP to RAM, and reverse proxy caching. Testing speed with tools like Google PageSpeed Insights is advised. Application optimizations alone can improve page load times from over 5 seconds to 3 seconds, while full server optimizations achieve over 1 second load times.
Yahoo has developed the de facto standard for building fast front-ends for websites. The bad news: you have to follow 34 rules to get there. The good news: I'll take a subset of those rules, explain them, and show how you can implement those rules in an automated fashion to minimize impact on developers and designers for your high-traffic website.
A technical guide on website speed optimization for webmasters. A complete goto guide for every publisher.
Front-end performance optimizing involves optimizing a website's HTML, CSS, JavaScript, and image files to achieve the fastest possible loading speed. This includes minimizing HTTP requests by combining files, compressing files, optimizing code by removing unused code and errors, leveraging browser caching, and parallelizing downloads across domains. The document outlines nine techniques for front-end optimization, such as optimizing file sizes, reducing download size through compression and caching, and minimizing HTTP requests through file combining and CSS sprites.
