Average load time. To get a general sense of the data this plots the average time it took to load each URL. The interesting piece here is that multiple foreign sites take a while to load (163.com, qq.com, gmw.cn, ..) - I suspect a big reason is that there's quite a bit of latency since I'm based in the US. Another observation is that many news sites tended to load slowly (huffingpost.com, cnn.com, cnet.com). The Google sites loaded extremely quickly (all less than 1 sec) as did Wikipedia.
As usual, the code’s up on GitHub.
