That kind of speed would make sense if you're sending and receiving over Wi-Fi (eg; you're installing from a laptop to your Switch). I'm biased, as my primary machine is usually docked on ethernet, and that ends up maxing out my install speed at ~15MBps due to the Switch's crappy wireless module.Me Personally, I get 12 MB install over usb with Goldleaf and usb, and with Awoo Installler I get 4.5 to 5.3 MB install over wifi. On the other hand my wireless router is crap, but still in some cases slow usb is still faster than wifi.
12MBps with Goldleaf's USB installs sounds about right.
