My Web Performance Dirty Secrets Fred wants to come clean and reveal to all his web performance dirty secrets – it's too much burden to bear. He's been guilty of some malpractices in the past and so are a lot of people in the industry! Time to take a stand and reveal it all. Do you want to know why popular websites are struggling when comes the holiday season? Why black magic is so popular in some web performance team? Why your brand new and shiny F5 load balancer can be sometime a real waste of money? Or why third-party can really spoil the … party? Best of all, you will learn that there is something call 'The Cloud' that is about to become your best buddy and will prevent you from keeping … dirty secrets.
