Performance is no more a curse

Performance is no more a curse

I bet you are writing unit tests for your apps; if not, you probably feel ashamed. But what about performance? Everyone is talking about it but very few people actually integrate performance into their development workflow... After some quick theory, I will show you how to use Blackfire that makes it so easy to profile your apps that you won't have any more excuses anymore for not doing it. Finally, I will talk about my new holy grail: Continuous Performance Profiling.
