I have one P2P Circuit from our HQ to a secondary office. the distance between them is approx 2kms. Earlier when the Circuit was delivered at that time we were having an RTT of 3-4ms. It is a 10Mbps Circuit and when there is traffic flowing on it, irrespective to the amount of Traffic, the Latency reaches to 300-400ms. But when I remove all the traffic from the Circuit then it gives a proper RTT of 2-3ms.
Can you suggest what could be the Issue?
