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. 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.
This section presents a list of freely available browser extensions for purposes of identifying areas of optimization across the web interface. Some of these tools (e.g. Google Pagespeed, Yahoo Yslow, etc.) have become standards with regards to Web Page Optimization for development teams around the world. We will be constantly updating this page with links to relevant tools. If you spot something that’s missing from this list please reach out to me over email.
