Some things I notice about your trace route, assuming your Internet connection was mostly idle at the time of the trace route.
Hop 2 indicates that you already have 200ms of latency before leaving your local network.
Hops 8 & 9 shows that the link between Italy and France (I think) is adding another approx 300ms.
Hops 9 & 10 looks like the link between France and the US, adding another 170ms or so.
Overall, I think your ISP, or the upstream provider that they use, has a really bad link to the west coast of the USA, at least at the time that you did the trace route.
