Magento

This week’s task was optimising Magento for large carts (100+ different products) and a profiler is a good tool to find small pieces of code that could be optimised. Blackfire was my choice, mostly because previous experience, but also because it is not a resource hog like Xdebug, which was taking around 6 minutes while Blackfire took only 20 seconds in the same type of request. Companion Blackfire works great to profile GET requests on the browser with the help of Companion, but it doesn’t allow you to profile POST requests. Also, Companion sends multiple requests to the same endpoint, but Magento’s place order is not stateless, so the first and all other request would differ substantially. ...
