Changing Time Zone

I updated my profile with system specs.  I am booting up a Window 7 system with LL on a USB Drive.  I am not sure what USB "Live" means. I installed LL onto a USB Flash drive.  I guess my question is, will I get better performance loading LL onto the HD or will it be more responsive using the USB as it is essentially an SSD?  BTW all USB ports on this machine are 2.0.  I also have 2.5GB of RAM, but profile would only let you choose whole numbers.

I ask these things because I certainly see an improvement, but I experience significant drag on things like youtube video.
