As we all know, China and the United States just opposite the earth, separated by the eldest brother of the Pacific. For the people of the two countries "friendship", network interoperability, China-US network, telephone and other data transmission through the Trans-regional Pacific submarine cable. At present, there are two direct submarine cable between China and America, one is china-uscablenetwork, the network capacity reaches 80Gbps. Mainland China landing Point is Shanghai Chongming Island and Shantou, the U.S. landing point is California San Luis obispo (between San Jose and Los Angeles). Another is the famous trans Pacific Cable, the design capacity reached a staggering 5.12Tbps, the mainland landing point for Shanghai (China Telecom) and Qingdao (Chinese unicom), the United States landing point for Oregon State Nedonna Beach. Both cables have been opened for commercial use, but from the results I have traceroute many times, TPE seems not yet open to the general broadband users. The bandwidth growth between China and the US is staggering, according to CNNIC statistics, with a bandwidth of 203980 MB between China Telecom and the United States at the end of 2008, while Netcom is 110456 MB. China Telecom currently has nodes in the west coast of Washington State in Seattle, California, San Jose, Los Angeles and Parahatu.

Then we choose the computer room server support or buy VPS, please select the closest to the room of the bank yo.

General Telecom/Netcom user access to the United States site network data transmission of the route first local ISP network, then the metropolitan area Network, then the provincial and municipal networks node, then the backbone network, finally from Shanghai and other exports, spanning more than 10,000 kilometers of the vast Pacific Ocean, in the United States of California/Oregon State landed. Network delay (latency) is above 200ms. Many people mistakenly think that g_f_w network filtering will affect the speed, but in fact, the impact can be ignored, the network delay in more than 200ms is mainly in the transmission distance is too long, the Japanese/Australian internet users of the United States network delay and the same as the mainland user, and European users across the Atlantic generally above 100ms.

If you are mobile users, bandwidth resources for the two giants to be less poor, mobile users are generally first south to Hong Kong to connect NTT's node, and then detour to the United States, the network delay reached a staggering seven hundred or eight hundred milliseconds. So if you want to play an American costume game or video, please do not use broadband that is provided by operators other than telecom or Unicom. such as Mobile, CRC, the Great Wall Broadband, Gehua cable, Tianwei and other local broadband operators, although cheap, because his broadband is not to force AH. 100M is also a cock, swap, delay large and so on.

This is the best place for mainland users to be located in the west coast of California, California's computer room is the most concentrated three, sanjose (San Jose), Fremont and Los Angeles. Among them, Sanjose and Fremont are located in the Bay Area, which is also the entrance of Silicon Valley.  

Thus according to my many years of experience, generally China to the United States the best ping value in 140ms (character and location very good time), normal in 200ms or so, if you hard to compare with the domestic 30ms, it is indeed defeated. Then you can choose to immigrate to the United States! But the measured 200ms delay, play the game, watch the video without pressure!
