in case of json extension we don't provide the program statistic

I'm not sure how to solve best this problem.... 

* to all json request => i will not show the statics because it takes to much time to compute for all the programs
*  only when we ask for more than 10 programs (limit parameter is > 10) => in case u ask for do many programs, the statics are not provided anymore because it will take too much time to compute

the more i think about it the more the second option seems better.
