In this talk, Benjamin from Tideways and Rik from Sparkables presents their recent learnings on Magento and PHP backend performance that they made from profiling data. This is a really powerful way to question assumptions that we all make about our code. Topics include
The ObjectManager and Native Lazy Objects in PHP 8.4
Examples how Magento core or third party plugins can do expensive work that we never expected them to.
Composer-patches and how it can help you work around Magento core or third party plugin bottlenecks.
