very good presentation style and a relevant topic. a tad more practical examples could have made it more understandable for those not too familiar with the topic.
very inspiring and well presented, given many useful concepts to deepen into in a small amount of time. glad to attend it
interesting and entertaining talk with a good overview of whats new for people like me who are to lazy to read release notes
Nice talk! The past and future of our working days.
very interesting project and a good reasoning why this is needed at all. a bit more demo would have been nice.
enthusiastic talk on a very interesting topic. i didn't mind staying a bit longer :-)
interesting talk and as somebody who has never written a php extension i got an impression of what it means. the talk structure was not overly clear to me.
very interesting and you could feel that the speaker really knows what he is talking about. a bit more context of when to optimize and how to spot bottlenecks woul have rounded it up.
As it was said, for many assertions the speaker didn't explained pros and cons. It was only a list of good practice and some or them are questionable. I wold have preferred a shorter list of arguments discussed more deeply
