Fabien Potencier discusses PHP performance optimization, focusing on using profilers (particularly Blackfire) to identify and fix performance bottlenecks. He explains that while PHP frameworks like Laravel and Symfony are often considered slow, the real performance issues usually stem from application code rather than the framework itself. The talk covers how to use profiling tools to measure performance metrics, set performance expectations through assertions, and integrate performance testing into development workflows.
Ben Ramsey presents a comprehensive overview of HTTP/2, explaining how it evolved from HTTP/1, its key features like server push and multiplexing, and how it impacts web development practices. He discusses the history of HTTP protocols, the limitations of HTTP/1, and how HTTP/2 addresses these issues while maintaining backwards compatibility. The talk covers both technical implementation details and practical considerations for developers adopting HTTP/2.
A detailed talk about the history and evolution of PHP, focusing on the development of PHP 7. The speaker discusses his early involvement with PHP in 1997, the performance improvements made in PHP 7 compared to previous versions, and the technical changes that enabled these improvements. The talk includes case studies showing real-world performance gains and discusses future plans for PHP development including JIT compilation.
Adam Wathan presents a comprehensive overview of Tailwind CSS, a utility-first CSS framework. He demonstrates how to effectively use Tailwind's utility classes, explains best practices for component extraction, and shows how to handle animations and responsive design. The talk includes practical examples of extending the framework and optimizing file size using PurgeCSS.
The talk focuses on database performance optimization in Laravel applications, specifically around Eloquent queries. Using a demo fishing social media app, the speaker demonstrates common performance pitfalls when working with Eloquent and presents solutions using sub-queries and relationship optimization. The presentation emphasizes the importance of monitoring metrics like memory usage, query count, and model hydration while showing how to avoid N+1 problems and excessive PHP memory usage when dealing with large datasets.
A technical deep dive into Laravel Livewire best practices and advanced concepts by Foil, focusing on performance optimization, security considerations, and database architecture. The talk covers strategies for improving Livewire component performance, implementing optimistic UIs, handling database replication for global applications, and securing public properties in Livewire components.
A detailed technical talk about Laravel Octane, explaining how it works internally, its benefits and gotchas. The speaker covers how Octane allows Laravel applications to run in a long-lived process instead of bootstrapping for each request, discusses different runtime drivers like Swoole and FrankenPHP, and explains concepts like non-blocking I/O and concurrent task execution. The talk focuses on understanding the underlying architecture rather than basic usage.
Jess Archer presents a detailed comparison between traditional OLTP databases like MySQL and analytical (OLAP) databases, focusing on ClickHouse. She demonstrates performance differences using a Stack Overflow dataset of 60M rows, showing how analytical databases excel at aggregation queries while traditional databases are better for row-level operations. The talk includes live demonstrations of query performance and explains internal workings of column-oriented vs row-oriented database storage.
A comprehensive talk about scaling Laravel applications, focusing on resource management and infrastructure. The speaker discusses common scaling challenges, strategies for managing memory and CPU resources, caching best practices, and horizontal/vertical scaling approaches. The talk emphasizes the importance of monitoring, stateless applications, and proper infrastructure automation for successful scaling.
A comprehensive demonstration of the Laravel Media Library package, showing how to handle file uploads, manage media collections, generate responsive images, and optimize file storage. The speaker walks through practical examples of adding media to models, handling downloads, working with different file systems like S3, and implementing responsive image loading with automatic thumbnail generation.
A comprehensive talk about database indexing fundamentals and best practices, focusing on MySQL/MariaDB. The speaker explains how B-tree indexes work, demonstrates common indexing pitfalls, and shows how to properly design indexes based on query patterns. Through live coding examples, he illustrates how to analyze query execution plans and optimize index usage for better performance.
This talk focuses on performance optimization in PHP applications, covering why it matters, how to measure it, and various tools and techniques for identifying and fixing performance issues. The speaker shares practical examples using tools like Xdebug, XHProf, and flame graphs while emphasizing the importance of measuring before optimizing and maintaining a balance between performance and code readability.
Tobias Petri discusses database scaling strategies in Laravel applications, focusing on the progression from single server to read replication to sharding. He emphasizes the importance of optimizing existing setups before moving to more complex solutions, warns about common pitfalls in each scaling approach, and explains how different scaling solutions fit different application needs. The talk includes practical examples using a hypothetical Laravel e-commerce platform selling conference tickets.
David Hemphill gives a talk about creative ways to use and reuse Laravel's built-in components for solving common development problems. He shares approaches for handling front-end filtering, database testing, data access patterns, and model scheduling by leveraging existing Laravel features like pipelines, database seeders, form requests, and the scheduler rather than reaching for third-party packages.
This talk focuses on how to effectively use HTML to improve website performance and accessibility. The speaker emphasizes the importance of using semantic HTML elements correctly instead of generic div elements, explains how HTML impacts the DOM and accessibility tree, and covers various HTML attributes and resource hints that can optimize page loading.
