Use Spdy to speedy the ios app's request delay, but the result is not very nice to me.

[philonpang]

the test result as followed is one url test, i am looking forward some person to give me some suggestions to solve the question.

the test Method is: the same devices(nearly 2,000 devices), 50%'s probability to use common http request when app startup, and 50%'s probability to use spdy requests.
