(RADIATOR) Loadbalance

[rcortez at info.com.ph]

hi hugh,

   does this mean if we ever encounter performance problem
(i.e. slow auth, lost stop records) we need to separate the 
authetication from accounting. and accquire additional radius 
server to handle accounitng packets. and may be, add a load balancing
server (radiator)to spread the work among 3 servers?

thanks,
ray
