Tools - Web Performance Optimization
What Is Web Performance Optimization
Web Performance Optimization is a key aspect of Systems Performance Engineering. A very large part of the engineering effort involved in delivering web based systems includes optimization of the web front-end which is part of delivering a great end user experience. This optimization includes focus on delivery of a great end user experience, User Interface that support delivery of a great end user experience and also optimization of delivery of the web assets (images, html, js, etc.) to the client. Web Performance Optimization takes into consideration device types, link performance, client (browser, etc.) type and various other factors that could impact the end user experience. Until recently the only way to identify obstacles to delivering a good end user experience was to use Packet Capture & Analysis tools like Wireshark or Fiddler. Things have changed a great deal over the last half a decade with numerous open initiatives out there aimed at assisting the web developer with finding areas of optimization across the interface.
Google makes some relevant recommendations with regards to web performance optimization -
- Focus on the user; the end goal isn’t to make your site perform fast on any specific device, it’s to ultimately make users happy.
- Respond to users immediately; acknowledge user input in under 100ms.
- When animating or scrolling, produce a frame in under 10ms.
- Maximize main thread idle time.
- Keep users engaged; deliver interactive content in under 1000ms.
