[Rdfapi-php-interest] rdfapi performance

[Ghislain <ghi...@lo...>]

Hi,

I'm going to implement a quite demanding application using rdfapi. I 
looked around and it seems the most comprehensive api in PHP. Congrat!

However, I'm a lit bit concerned about the performance. For instance, 
the ResModel is a very convenient interface but looking at the code, I 
realize the overhead may be important with numerous "new" and 
"resNode2Node" calls. Does somebody know about rdfapi performance, 
especially ResModel versus MemModel ?

Cheers, Ghislain.

As resModel is an abstraction layer above memModel it is of course a bit
slower.

Daniel Westphal did some benchmarks when he implemented resModel. I =
think
his test showed, that resModel is only about 10% slower than memModel =
(which
surprised me).

Daniel, so you still have the exact figures somewhere?
