Can you rule out the possibility that its a networking issue on your end?
For example, depending on your connection type/medium (wired or wireless), your speeds can be lower on wireless (even on wired if it's less than 100Mbit or configured wrong)
Also, some older routers only have a 10BaseT connection to the WAN interface, so you would see speeds Under 10Mbit.
What is your connection setup exactly (router? wired/wireless/usb?, etc...)
I have it directly wired, no router yet. I have it wired with ethernet cable, not usb.
