"Automatic Web Page Optimisation in Pure PHP by Albert Peschar
We all know slow sites suck. According to research by Amazon, customers buy more when a site is responsive. Google ranks fast sites better.
Using a WordPress case study, I'll take you on a journey through the jungle of web page performance. You'll learn to discern the many factors that are important in performance. I'll show you the techniques, tricks and tools used to overcome slowness.
You'll learn about image, script and stylesheet optimization, roundtrip minimization and why it's important. In addition, you'll discover a unique tool that allows you to do all that automatically.
After this talk you will be able to confidently measure a website's performance, and diagnose the reasons for it being slow. You'll know what to fix and how, and make your customers happy.
