[OpenSIPS-Users] Load Balancer

[Bogdan-Andrei Iancu]

Hi Rajib,

the load of each trunk is calculated each time the "load_balance()" 
function is called -> the load is a higly dynamic info and needs to be 
evaluated each time load balancing needs to be done. There is no way to 
cache/store any info related to previous less loaded trunk.

Anyhow 100+ trunks does not mean a lot ;)

Regards,
Bogdan
