Thanks for clarification @tharun_n so you have maximum 225 Mbps bandwidth (with 10% reserved) for configuration you use. The bandwidth is enough for 200 streams of 1 Mbps each, or 100 incoming RTSP streams and 100 outgoing WebRTC streams (one per each subscriber). This is more than a maximum awaiting capacity by CPU (but not much more).
Please consider this while load testing. May be you have to choose a more powerful configuration with more bandwidth.
