[OpenSIPS-Users] Access to statistics variables from within script

[Bogdan-Andrei Iancu]

Hi Richard,

1 important comment here - the global vars are something more powerful 
than statistic vars. And of course, they come with more penalties. 
Operating with the global vars requires internal locking (over the 
variable) - this may lead to a general slowdown of opensips as all the 
procs will keep syncronizing over the lock for the this vars. The stat 
vars are using atomic ops (internally) and they do not require locking.

just my 2 cents on this,
Bogdan
