Hello,
Primary, very thanks for your service, very serious and complete. Now, the real idea which created this post :
Many extension are available yet, but one or two more could be enable. I think that :
Apc : or another cache accelerator would be very usefull and would permit to have more hardware (better for hd and a little cpu) and software (less loading time) efficiencyintl : usefull functions
With hope you will agree.
The last advantages is with extensions the servers become symfony2 and drupal compliant.
Best regards,
Surae
