# Performance At first, your application was fast and smooth, and using it was easy. Then more data was added. And more people started using it. And then it began to slow down. This slowness is impacting your business! Amazon found out that for every 100ms delay in loading web pages, they were losing 1% of their sales. And 40% of people will abandon a website if it loads in more than 3s. And guess what? It is even slower on mobile platforms! If a website takes time to load on your comfortable DSL line, imagine that on a phone through a data plan. Improving the performance of your website will make a better experience for your visitors, and result in more sales. Do you stand losing money? I can help you fix this at different levels: * reducing the network latency * optimizing the server side code * making the display smooth * improve the mobile experience
