The speed of access is critical to a website. It is the basis of user experience, without the advantage of the speed of access, the site is designed again exquisite also difficult to stay the user, this point of no doubt. Especially for today's increasingly bloated web, a few megabytes of JS and CSS, endless AJAX requests, in improving the user experience, but also at the expense of speed.

How to improve the speed of Web site access, has been a major site research topics, from a large level to do CDN, multi-level cache to the technical level of the compression optimization code. This kind of article is countless, I will not repeat. What I'm discussing today is a much lower level, often overlooked factor that affects server speed--the location of servers. Most webmasters don't have much concept of how to choose a server. Many people don't even know where their servers are. In the construction station, but also simply consider the "record", "price" and the like, in the "domestic mainframe" and "foreign host" among the two selected. How much does the location of the server affect the speed of the website? Let's take a look at a set of data (figure I):

  

(Figure I: Data source: Hostucan website monitoring tool)

The chart is a Hostucan website monitoring tool for monitoring records of a U.S. website. A total of five detection points were selected, of which four detected points in the United States: Fremont (Fremont, Midwest), Dallas (Dallas, South), Newark (Newark, East), Atlanta (6188.html "> Atlanta, South). And a British monitoring point: London.

It is not hard to see that the pace of surveillance in the United States is basically flat. London, by contrast, is generally less fast than the United States.

Look at another set of data (Figure II):

  

(Figure II)

Also on the previous site, this time, the green solid line in the figure is five monitoring points of the average access speed change. To test, on October 31, the site was transferred from a U.S. server to a server in Linode Japan. In the statistics diagram, the impact of this migration on the server access speed is clearly shown (the right protuberance in the figure).

It follows that Asia's visit to the United States is about 4 to 5 times times slower than its own in the United States. Therefore, it is strongly recommended that those who dislike domestic formalities, and the server relocated to foreign webmaster, as far as possible to choose the host of Asian computer room. Small site, here is recommended Linode Tokyo VPS. A larger site, at the same time can consider SoftLayer Singapore's cloud host.

After that, we turn our eyes back to the country (figure III):

  

(Figure III)

This time, the website is located in Tokyo, Japan. The red is Shanghai Telecom monitoring point, yellow for the Henan unicom monitoring point. Green for the US Atlanta monitoring point.

This time, the speed of China's failure is really miserable ah. Even the Shanghai room near Tokyo. The average rate of visits is also slower than the visit from the United States to Tokyo. Not only that, the packet loss rate of access is also quite serious. As for the Hunan unicom "* * * ..." Of course, do not exclude the packet into the domestic "security" This step spent a lot of time.

Overall, domestic access to foreign servers is generally slower than abroad. Considering the same configuration of domestic host prices are also higher some of this, RTHK and Asia's host is preferred. However, put on a blog, forum, entertain a fair. Really want to do for the domestic large-scale web site, not the record must not be. For the record, the server can only be placed at home.

In addition to the speed of access, there are many important concerns about server location. Like hardware facilities, disaster preparedness, technical support, etc., are also factors to consider. Alas, the first step of building a station is so tangled. Sure enough, stationmaster is a hard work.

However, since when the webmaster, is sure to be happy the most important.
