The SoC is connected with 2.5Gbit (full duplex) to the switch. There shouldn’t be any bottlenecks on the network side for a near 2Gbit total throughput per port.
The Marvell SoC is 28nm.
Heatsink + fan is probably overkill. Marvell claims less than 1W TDP on the SOC.
A really small heatsink just to dissipate the heat should be more than enough.
Simultaneous 900Mbit (1800Mbit total)? Was it NAT/firewalled? Sounds promising.
