What changed internally?

Interesting topic but boring presentation

Congrats nikita, one of the best presentations i've seen on a php conf. I'm a hardcore user of iter and I come to BCN conf to see you talk. For me, as a developer, maybe the topic is not something that i will use but I think its very interesting

Hope to see you again!

Very interesting topic!

The topic is interesting but not the type of talk I expected specially when can sum it all to: PHP 7 is faster because it uses less memory.

Extremely interesting and it was exciting to hear the changes from a core developer because he could talk about the intricacies. Even though it is not applicable to my day to day I really enjoyed the talk

Good talk tough concepts explained in a clear way

A good vision of PHP internals and improvements, not very common to see a talk like this in conferences. Congratulations.

Good talk, with interesting details, but hard to follow due to the aridity of the concepts and lack of rhythm.

Quite an informative talk about a topic hardly related to my everyday work.

The speaker's monotone and slow pace ultimately made the talk hard to follow.

Taking into account the complexity of the concepts exposed, I think the talk was good and the slides were quite explanatory.

I really enjoyed the intricacies about internal PHP 7 changes, though many found it boring and "an implementation detail". I suppose they've never even opened the Symfony's Request.php file to know how it works under the hood.

I encourage Nikita to make more talks and become a better speaker, so he can share with us more and more of his work.

The content of this talk are no easy to follow completely by the common developer who has no experience with internals, but despite that is really interesting to have a look at how things work under the hood
