Radius and Mikrotik NAS latency

Dear friends,

i have set a new management solution for my existing customers.

i have installed Jaze ISP Manager ( listed in MADE for Mikrotik site) as Radius and Mikrotik CCR 1036 EM as NAS.

but there is a problem,

i just open command prompt and set a ping to google public dns and also i ping yahoo and keep them running
while ping is running in the back ground , while i start browsing, downloading or streaming the latency for both pings rises.
and some times even goes in 400 ms to 500 ms

how ever there is this no bad effect on browsing or streaming at all even if it goes to 400ms -500ms. but u see when a non technical customer of mine see this it appears like an issue for him.

and this happen with each customer of mine. how to make those ping statble during internet use or downloading and streaming?

Regards
