From my tests it appears the Los Angeles, CA - Chrome - DSL has a bottleneck to download content consistently as there are high response times due to what appears to be bandwith related. This skews test metrics.
My concern are the assets that are served via CDN Edgecast. www.lenovo.com www01.lenovo.com,www02.lenovo.com
Los Angeles, CA - Chrome - Cable → no bottlnecks from CDN(Edgecast).
