This document summarizes an presentation about optimizing WordPress site speed. It introduces the presenter Ivan Kristianto and his background with WordPress. It then discusses how fast a site needs to be, with metrics on loading times from various studies. The bulk of the document outlines specific techniques for optimizing WordPress sites for speed, including server configuration options, plugins like LiteSpeed Cache, and settings within that plugin. It then shares results of speed tests on the presenter's site using tools like GTMetrix, Pingdom, and WebPageTest to demonstrate how these optimizations were able to make the site fast even on a shared hosting plan.

Nginx was created as a lightweight web server to address limitations in Apache's architecture. It uses an asynchronous event-driven architecture that scales well under heavy load. Nginx development began in 2002 and version 1.0 was released in 2011. Features have evolved over time to include FastCGI, SSL, caching, streaming, and WebSockets support. The future may include optimizations like asynchronous I/O, multithreading, and dynamic configuration.

This document discusses how caching can improve website speed. It begins by explaining how websites load files sequentially and sets a goal of under 2 seconds. It recommends getting a fast web host as the first step, then optimizing images, code minification/concatenation, and lazy loading. There are different types of caches like browser, server, and memcache caches that store content to reduce load times. Common caching plugins like WP Super Cache and W3 Total Cache are recommended, or paying for WP Rocket for e-commerce sites. The key steps are to get a fast host, optimize the site, then cache it to improve performance.

This document provides an overview of Microsoft Azure Service Bus and compares it to Azure Queues. Service Bus allows applications and services to communicate over reliable messaging even if they are not connected all the time. It supports queuing and publish/subscribe capabilities. Service Bus Queues offer more features than Azure Queues, including larger message sizes, unlimited time-to-live for messages, and publish/subscribe capabilities using topics and subscriptions. The document also describes how to configure applications to use Service Bus Queues and Relay for communication between apps and services.

This document provides best practices for Magento hosting. It discusses using proper permissions for files and directories, PHP configurations like using APC caching and increasing memory limits. It recommends using PHP-FPM with Apache or Nginx as the web server. For the database, it suggests using Percona MySQL and provides tuning tips. It outlines a caching strategy using Redis and Memcache with Magento's built-in caching and recommends using Varnish for full page caching. The document concludes with links for more information on its caching and performance recommendations.

This document introduces various technologies used for live-reloading WordPress sites including Node, NPM, Bower, SASS, LibSASS, BrowserSync, Zurb Foundation, and Gulp.js. It recommends using a jumpstart WordPress base that has these technologies preconfigured to simplify setup. The document then explains how each technology works and how to install dependencies, watch files for changes, and run tasks with Gulp to enable live page reloading in the browser.

This document provides tips for boosting performance in React and Webpack applications. It discusses various optimizations that can improve build speed and bundle size for development and production environments. Some of the key recommendations include using PureComponent to minimize unnecessary re-renders, avoiding large JSX blocks, code splitting, tree shaking with Webpack 2, and leveraging tools like HappyPack, UglifyJS, and CSS loaders.

1) SSDs provide significantly better performance than HDDs for WordPress.com, reducing costs by 75% while improving performance and capacity 6 times. 2) An experiment replacing HDD RAID with SSDs was very successful, but initial production deployment had critical bugs and required restarting the migration process. 3) While SSDs save money and users' time, maximizing their performance requires substantial research, testing, and software optimization from system administrators.

WordPress has thousands of themes and plugins freely available. Not all of them are coded beautifully or tested with big WordPress sites. When a bad piece of code goes live on a WordPress site, it can slow down site and even crash server in some cases. Goal of this session is to show how EasyEngine and other tools/techniques can be used to debug performance bottleneck on a WordPress site. This will make life of developers and system admins easy.

Your self-hosted WordPress site is quickly growing in popularity and page views. Or maybe you want to get away from that costly enterprise CMS currently on your plate and adopt a delectable, open-source platform. There are many reasons you might need the performance and redundancy of a clustered server solution, and I’ll show you how to mix up the ingredients needed to throw together a successful cloud-hosted WordPress environment that’s right for you. We’ll talk about common multi-server configurations, from cheap and quick for the cost-conscious business, to robust and complex for the high level of control an enterprise demands.

The document discusses how HHVM (HipHop Virtual Machine), a just-in-time compiler created by Facebook, can improve the performance of PHP-based websites like WordPress by compiling PHP to bytecode faster than traditional PHP processing. It provides benchmarks showing HHVM's performance advantages over PHP-FPM and describes tools like XHProf that can help optimize WordPress sites to take advantage of HHVM's capabilities. While HHVM has risks with poorly coded themes/plugins, its performance gains make it worth considering as an alternative PHP processor.

Question: Can you run a Fortune 500 Drupal 8 website from your basement, on a cluster of Raspberry Pi computers? Answer: See this presentation to find out! Jeff Geerling is the author of Ansible for DevOps and a Technical Architect at Acquia, who has worked on many large and small scale Drupal websites.
