i would like to know for sure why it does not reach the same speed as PC or a PS5.
In a nut shell......
Probably asking to much of a $30 SBC (Single Board Computer)
Haven't peeked around this board so not sure what board it's using, but typically........
These boards are based on a SoC (System on a Chip)
They do not have dedicated controllers like a PC would have a dedicated
Ethernet controller where as this board would have the Ethernet controller
built into the SoC
I'm sure the SoC ethernet controller is a "gigabit" controller but.....
The data has to get from the Ethernet port on the bus to the SoC controller via the Bus
Not sure what bus this board has on it, but let's assume it's a single lane PCIe V2 bus.
The theoretical maximum through put on PCIe V2 (single lane) would be around 500mps
Which would mean 1gig data through put would be saturating the bus around 500mps.
Also depends on what other devices are on the bus and active. Like the USB ports etc.
Moving to newer boards might get you something like a PCIe V3 bus, They keep improving
them while maintaining price points. Maybe the next gen Z10? has upgraded bus, like PCIe V3
which would get you up to the 1gig bus through put.
I'm sure your issue is bus related.
PC's have dedicated ethernet controllers and faster multi-lane buses.
