Some developers underestimate the cost of building slow webapps. For example Magento. Magento is extremely slow. I know companies who pay hundreds of dollars for hosting per month to make it faster. Working with Magento always means thinking about scalability and complex architecture. But in reality webservers are extremely fast, even cheap ones. If Magento was built as a good app you would only start to worry about scalability at the time you had a million dollar webshop.
