This seems really strange to me, but on my mbp i have 10.6.8 completely updated and bootcamp of windows 7-64bit with all the latest drivers and updates installed, and i get 2 different speeds on each side. using speedtest.net, on the OSX side i get about 90 Mbps then on the PC side i only get 15 Mbps. i should mention i have the latest time capsule and the newest Motorola docsis 3.0 modem. is there any reason i should be getting the 2 different speeds?
