alt Hacker NewsYou can hit 10 gig aggregate on an A57 quite easily, given standard memory bandwidth (I've done it). They must be doing something stupid on the software side, like too many copies. Or if you're trying to shove 10 gig in one flow at 1500 mtu yeah that might be painful.
As I recall there were some people on reddit who got the UNAS Pro 8 up to 10gig, but yeah it was only through some level of software tweaks or network stack config or something. From the factory my understanding is that it struggles.
