10997,Upload speed problem for virtualized Windows 7 or XP and NAT,Ladislav Nesnera,,"I have the same problem as described here - http://www.appleimac27.com/2012/08/25/how-to-fix-windows-8-virtualbox-upload-speed-problem-on-imac/ i.e. upload is significantly lower in the guest then in the host (0.18 versus 2.75 Mbit/s)

I can't use suggested workaround (switch to Bridge) because it is impossible for 3G modem.
Very Interesting is that virtualized Ubuntu has full upload speed with NAT
