Heavy Web Optimization: Frontend

This presentation was presented on October 31, 2012 at BarCamp Tampa Bay, FL. It was made to discuss the basics of Optimizing your WordPress Site.

WordPress Performance 101 provides tips to optimize WordPress site performance in 3 sentences: It discusses how poor performance can negatively impact users, money and SEO, and outlines steps to diagnose a site using tools to measure speed before and after installing caching plugins like W3 Total Cache and a CDN like Cloudflare. Proper server configuration, hosting, plugin usage, image optimization and caching are emphasized as ways to boost speed for a better user and search engine experience.

Front end optimization is important because 80% of end-user response time is spent on the front-end and front-end optimization can cut page load times by 25-50%. Page load times significantly impact user experience and business metrics. Tools like Yslow and Google PageSpeed can help identify optimization opportunities. Image optimization, minimizing HTTP requests by combining files, and reducing payload sizes are some techniques that should be applied from the start of a project. Progressive page loading, splitting components across domains, browser caching, and preloading components can further improve performance.

The document discusses various debugging techniques in WordPress, including: 1. Using WP_DEBUG, SCRIPT_DEBUG, and SAVEQUERIES constants to enable debugging and view queries. 2. Installing plugins like the Debug Bar and Log Deprecated Notices to aid debugging. 3. Checking for issues like permissions, JavaScript errors, redirects, and rewrite rules when troubleshooting. 4. Tips for local development including using hosts files and output buffering to replace live URLs. 5. Mention of tools like Xdebug and unit testing to improve the debugging process.

WordPress Optimization This presentation discusses optimizing WordPress sites for speed and performance. There are many layers that can be optimized including: 1. Front-end optimizations like using a CDN, image compression, browser caching, and minifying CSS and JavaScript. 2. Optimizing the theme and plugins by removing unused code and plugins, updating WordPress core, and ensuring good coding practices. 3. Back-end optimizations like caching pages and objects, using a reverse proxy, optimizing the database, and ensuring a fast web and database server. The presenter provides many specific techniques and tools to optimize at each level like W3 Total Cache, Nginx, Memcached, and MySQL

The presentation focuses on providing information how to setup hosting servers to use Nginx/Varnish for caching Drupal websites. It features the SiteGround SuperCacher and gives valuable information about how reverse proxies work and how to make a Drupal 7/8 website cache-able by Nginx and Varnish.

WordPress is my favorite computer asset, but it's very vulnerable to attack from the bad clowns ;-) This presentation from WordCamp Atlanta 2012 is my system of handling WordPress security without getting too geeky.

Today, a web page can be delivered to desktop computers, televisions, or handheld devices like tablets or phones. While a technique like responsive design helps ensure that our web sites look good across that spectrum of devices we may forget that we need to make sure that our web sites also perform well across that same spectrum. More and more of our users are shifting their Internet usage to these more varied platforms and connection speeds with some moving entirely to mobile Internet. In this session we’ll look at the tools that can help you understand, measure and improve the web performance of your web sites and applications. The talk will also discuss how new server-side techniques might help us optimize our front-end performance. Finally, since the best way to test is to have devices in your hand, we’ll discuss some tips for getting your hands on them cheaply. This presentation builds upon Dave’s “Optimization for Mobile” chapter in Smashing Magazine’s “The Mobile Book.” This talk was given at the Responsive Web Design Summit hosted by Environments for Humans.

While the principles of responsive web design can make sites look better on mobile devices, they don’t necessarily load faster than a site designed for desktops. And as more and more sophisticated WordPress themes emerge, with their multiple options and fancy sliders, websites just keep getting more and more bloated. This presentation will help cut out the junk that’s larding up your sites so you can better meet the demand of users wanting fast-loading user experiences–no matter the device or connection.

This document discusses PHP standards and how case sensitivity can cause issues when following PSR-0 for autoloading. It covers the PSR-0, PSR-1, and PSR-2 standards for namespaces, classes, methods and other PHP coding conventions. The main issue discussed is how case sensitivity in file paths can break PSR-0 autoloading if class names don't match file paths, requiring all URLs to be changed. The suggested solution is to use a classmap to map namespaces to file paths to resolve this issue.

This document discusses microservices architecture and Docker. It begins with an overview of monolithic versus microservices approaches. Key lessons learned with microservices include bounded context, service communication using external requests, internal requests, and message queues.
