Oups !

The delay clearly shows in the profiler, the import statement was executed 
before I start profiling.  

I have the following log :

It seems clear to me that either we our DOM implementation is really
unefficient or my model is too complex.  Having 40 entities in my
model, I think it should be easy to parse.

Anyone had the same problem ?

Any quick solutions ?
