Default [Q] Limited Tether Speed In Windows

I've noticed that, when using CyanogenMod wifi hotspot, I get nowhere near the device speeds for download and upload. I get quite near max speeds when tethered with another Android device like my Nexus 7, but when I tether with my Windows laptop I get speeds of around 2-3Mbps out of the tested 16+Mbps available on LTE. Is this just a network stack issue, or is there something else? It has been consistent between nightlies and from CM10.1 through CM11.
