phpng looks promising !
- the changes related to php's internal hashtables and the way pointers are used -
If they are doing what i think they might be doing this could bring down that crazy ram usage on 64 bit platforms quite a lot -
and make a real difference for existing code right now!
That is what is getting me excited about phpng.
I just hope if there is any merger that promise of much more sensible ram usage on increasingly common 64bit platforma does not end up being left behind in those priorities!
