[Kamailio-Users] Demerits of using normal Authentication insted of radius or diameter auth

Hello guys..... Recent now i had started taking keen interest in kamailio. I was testing kamailio, and i had test it under two scenario. first of all let me tell u about my configuration. I am testing on normal Desktop pc, installed kamailio,mysql, radius everything on same pc. I am using MYSQL anyway for both sort of testing. When i test with radius authentication, means using radius_www_authorize at max i am getting around 500 cps for Registration, but when i use normal www_authorize i am getting around 2000 CPS.... whopping difference guys..... So, i was wondering what is merits and demerits of not using Radius based authentication. Is it insecure if i use normal Authentication? Its not in my knowledge that radius do encryption...so i dont think by using radius it provides more security. What is your opinions about it? -- Regards, Hemanshu Patel M: 09601295238
