Not my area of expertise, but those speed test, page loading specifications are affected by conditions at the time you use them
I have experimented a little using one of my VSD websites which i uploaded to a server i know is in UK (where I am) another which is unknown, one for certain is in USA and SDRIVE (who knows where that is

)
Having cleared cache etc from 1 pc i tried each one in turn a few days later ( morning, evening, night) and the resulting upload speed at each server varied quite dramatically both from time of day, and from server to server.
At present the wedding car site in my signature on SDRIVE is in general loading fairly consistently slightly faster than it used to when hosted on JH.com but there have been days when i have tried it and the home page has taken 10 seconds to load, normally a fraction of that
Also i tend to do Ctrl F5 numerous times to see if i get a variation over a few minutes, and i often see quite a considerable difference within a few minutes
Good to test regularly yourself i trust this more than any statistic sites.
