Allowed memory size of X bytes exhausted

At the beginning of the talk it was sometimes hard to keep being interested, but when PHP was more involved it got easier to listen to and it turned out to be a pretty interesting talk.

It was fun learning about PHP Internals and how the language and memory manager actually work on the machine level.

In-depth technical talk, which is good for me, and it clarified some points I've always wondered about while measuring memory from inside PHP.
I thought there would have been more time dedicated to the common tasks that exhaust memory, like database extractions or XML parsed in one-shot.

interesting stuff. glad i studied computer science, otherwise would have been hard to follow. to my taste it could have been more clearly structured, had sometimes problems following.

Very interesting subject, never seen a talk going so deep on the ZMM and unix memory management. It was a bit hard to follow in the beginning, but when PHP got involved it was better.

Good to have a more advanced talk. I found it easy tot follow with had a good build up from Unix and memory to how PHP performs with memory. I sure hope tot attend the tutorial you have planned.

The way you explained the Unix and mem usage could use some work, but well done

I sure hope tot attend the tutorial you have planned.

Nice topic! Learned alot.

It only shame that the slides are not online.

Interesting talk, with a behind-the-scenes look at the Zend MM. What would make it even better would be spending a bit more time on some of the common memory hogging pitfalls and how to prevent these from happening (you did mention some of the basic things, would have loved some more).

There was only technical details about memory management, no tips and tricks as I was expecting...

A very interesting talk. The material was quite good. The one thing I would suggest is providing a little bit more flow to the presentation. At times it felt like it jumped around and lacked a consistent message.

Perhaps some more "high level" info could be provided (such as the memory overhead of a Zval, or the memory overhead of an array/array element).

As it stood, it was extremely informative and showed the power of the Zend memory manager. I would definitely recommend this talk for anyone who wants to understand what's going on under the hood a little more.

Very interesting in depth talk. I can imagine that without a little bit of knowledge on PHP's internals and C one could have gotten lost quite fast. Still it is very good to have more advanced topics on conferences.

Very good and advanced talk. I really liked the in depth view of Zend MM.

Good insides of the Zend MM. Without a CS degree I would be a little lost. But for me one of the best talks at the conference in relation to the depth.
I will certainly check out the 'php-memory-profiler'.
