It depends on the implementation, I'm sure, to some degree. With my Olympus E-M1 using Olympus Share, full resolution 16 mpixel JPEGs transfer in under two seconds apiece. With the Nikon D750, it runs just a little longer for 24 mpixel JPEGs. The Sony A7, also 24 mpixel, was a bit slower than that.
I'm not sure that any of them do wireless transfer of raw files, like the EyeFi Pro cards. I have one of those too and find its performance inconsistent and unreliable. I've not used any of the WiFi equipped Pentax bodies.
