5 minutes output rate extremely low on serial port: ping timing >400ms

Hello Everyone, I just changed my router on service provider end, and now the user is not getting stable connection from the server. Usually the ping takes 60 ms from server to the end user, now when I changed the router it is taking around >400ms of time. When I use old router, it agains come back to 60ms. I am just made all the configuration of new router similar to the old. Need your help on it. This specific connection is the only problematic part on this router, I have tried changing ports and cables already, still the issue is not resolved. Below is the output of the serial link:
