Drupal performance optimization Best Practices

Some practical ways to speed up your WordPress website. Looking at plugins, configurations, do's & don'ts, server software and hardware changes.

Overview of using cache on websites and some of the implementations of improving your sites performance through cache.

PHP comes pre-installed with all modules by default, which can lead to heavy processing. It is better to compile PHP from source and only install required modules. Lightweight web servers like Nginx with PHP-FPM are faster than Apache for static and dynamic content since PHP execution is native rather than module-based. Caching, a CDN, Memcache, and optimizing WordPress, MySQL, and plugins can improve performance. Security measures include restricting access, removing default accounts and files, strong file permissions, and installing security modules.

Web caching provides several benefits including bandwidth savings, reducing server load, and decreasing network latency. It works by intercepting HTTP requests and checking a local cache for the requested object before going to the origin server. Different caching approaches include proxy caching, reverse proxy caching, transparent proxy caching, and hierarchical caching. New techniques like adaptive caching and push caching aim to dynamically optimize cache placement near popular content or users.

This document discusses scalable web application architecture. It describes using load balancing and database replication across multiple servers to handle high traffic volumes. It emphasizes using caching at various levels (PHP, databases, CDNs) and preprocessing data to improve performance. A CDN is recommended for distributing static resources globally to reduce latency and failure risk.

Did you know that 80% to 90% of the user's page-load time comes from components outside the firewall? Optimizing performance on the front end (e.g. from the client side) can enhance the user experience by reducing the response times of your web pages and making them load and render much faster.

This slide is about the basics of web performance gives the insite of all the things we can do to achieve high performing web apps

This document discusses web performance optimization and provides guidance on ensuring high performance web applications. It covers why performance is important, key performance metrics to measure, common areas to profile like client and server-side processing, requirements for performance testing like goals and load thresholds, and tools for performance testing and profiling like JMeter, dotTrace and SQL Server Profiler. The document also outlines best practices for integrating performance testing into the development workflow when issues are found or time allows before a release.

A brief overview of caching mechanisms in a web application. Taking a look at the different layers of caching and how to utilize them in a PHP code base. We also compare Redis and MemCached discussing their advantages and disadvantages.

The document discusses optimizing WordPress performance. It recommends minimizing frontend assets like images, implementing caching for assets and application chunks, optimizing themes and plugins, and choosing efficient server setups. Specific plugins like W3 Total Cache and a CDN can improve performance by up to 10 times by caching static content. Nginx is presented as a faster alternative to Apache. Overall, the key takeaways are to simplify code, minimize requests, optimize caching, and reduce payload sizes to improve perceived and actual performance.

The document discusses various techniques for optimizing web performance, ranging from beginner to advanced levels. At the beginner level, it recommends avoiding redirects, enabling client-side caching, and reducing DOM elements. At the medium level, it suggests minifying JavaScript and CSS. More advanced techniques include image compression, combining files, and server-side gzip compression. The document also provides optimization tips for databases like MongoDB and recommends using asynchronous and non-blocking I/O for costly operations. It advocates for client-side templating to reduce bandwidth usage and improve cacheability.

Rami Jarvinen discusses optimizing performance on Drupal sites. He outlines several caching layers that can be implemented including PHP opcode caching, Drupal internal caching, page caching, and reverse proxy caching using Boost or Varnish. He also discusses scaling Drupal through techniques such as MySQL master-slave configuration, serving static files from Nginx/lighttpd, and adding frontend servers. Profiling with tools like Xdebug can help identify SQL bottlenecks to optimize. The optimal caching and performance strategy depends on each site's specific usage and hosting environment.

This document discusses how bookmarklets can function as applications by interacting with web pages in a secure manner. It describes how the bookmarklet uses elementFromPoint for fast hit detection, resets CSS to robustly render its UI, and transmits data to a server through signed cross-domain POST messages for security. Examples of embedding the bookmarklet code on a page and customizing its appearance are also provided.

What does it mean when someone says “My Site is slow now”? What is page speed? How do you measure it? How can you make it faster? We’ll try to answer these questions, provide you with a set of tools to use and explain how this relates to your server load. We will cover: - What is page load speed? – Tools used to measure performance of your pages and site – Six Key Improvements to make Drupal “run fast” ++ Performance Module settings and how they work ++ Caching – biggest gainer and how to implement Boost ++ Other quick hits: off loading search, tweaking settings & why running crons is important ++ Ask your host about APC and how to make sure its set up correctly ++ Dare we look at the database? Easy changes that will help a lot! - Monitoring Best practices – what to set up to make sure you know what is going on with your server – What if you get slashdoted? Recommendation on how to quickly take cover from a rhino.

This document provides an overview of scaling DotNetNuke in the cloud. It discusses infrastructure as a service models and configuring DotNetNuke for highly available, load balanced environments. Specific topics covered include setting up availability zones, load balancers, configuring web servers uniformly, replicating files, database mirroring, caching, and scheduling tasks. References are provided for additional resources on topics like shared configuration, distributed file system replication, and setting up application request routing.

Matteo Moretti discusses scaling PHP applications. He covers scaling the web server, sessions, database, filesystem, asynchronous tasks, and logging. The key aspects are decoupling services, using caching, moving to external services like Redis, S3, and RabbitMQ, and allowing those services to scale automatically using techniques like auto-scaling. Sharding the database is difficult to implement and should only be done if really needed.

This document discusses various techniques for improving the frontend performance of Drupal websites. It begins by introducing the speaker and describing the goals of the presentation. The bulk of the document then provides recommendations in three areas: backend server optimizations like caching, parallel downloads and gzip compression; tools for measuring performance; and frontend optimizations like minimizing requests, lazy loading images, and improving CSS and JavaScript. The document encourages proper performance diagnosis and defines goals before implementing solutions.
