Hello Koyel I think using a 10gbps nic card, a processor with 3.6GHz clockspeed, DDR4 RAM with an nvme ssd or ssd should be fine.

I only know we have 10 gbps servers so I was asking if that is not enough to ensure that data rate or something more is needed. I was expecting the system requirements to be outlined for the mentioned data rate.
