I am at #MagentoImagine 2019 this year at the Wynn Hotel in Las Vegas. Great food and fun times networking. What follows is a recap of some of the hottest panel topics in Magento development. This post is on Performance Profiling: Tools of the Trade.

HTTParchive.org is a huge DB of crawling results and performance metrics, which can be flitered by Magento websites. Magento utilizes these as a baseline to improve on for Magento 2 core development.
