I'm not sure what using wget is supposed to show. Using it 25 times in a row on a completely stable, completely idle 25mbps connection, I get speeds/times that vary by 100% consistently

(IE min is 496k/s, max is 895k/s, average is about 600k/s)

Using wget is a completely useless benchmark, from what I can tell. Using apache's little benchmark tool I get about 255ms vs 180ms average for 100 requests to each.

The interesting part is that for ajax.googleapis.com I get:

  Connection Times (ms)
                min  mean[+/-sd] median   max
  Connect:      175  228  28.2    227     306
  Processing:     0   12  15.1      8      90
  Waiting:        0    0   0.0      0       0
  Total:        189  240  29.8    235     350

and for cloudflare I get:

  Connection Times (ms)
                min  mean[+/-sd] median   max
  Connect:       19   28  13.1     25     125
  Processing:   125  155  28.0    146     246
  Waiting:       21   28   6.5     27      65
  Total:        144  182  30.7    175     271

IE for google, all the time is in actually getting a connection and getting the bits, whereas, for cloudflare, there is actually some time waiting for their servers.

Using 5 concurrent requests actually gives me a massive advantage for google (cloudflare takes roughly the same time, google goes 4 times faster)
