Web页面响应时间

https://bugzilla.mozilla.org/show_bug.cgi?id=488270

 

The goal is to provide an info for web developers that can be used to

analyze page load performance. This info should be composed from detailed

timings for each network request made by the monitored page.

 

The ideal timing info (for each request) should describe following

phases:

 

DNS Lookup: DNS Resolution time

Connecting: time required to create a TCP connection.

Blocking: time spent in a queue waiting for a network connection.

Sending: time required to send HTTP request.

Waiting: waiting for a response from the server.

Receiving: time required to read entire response from the server (and/

or time required to read from cache). In case of partial cache read it should

be possible to measure both times.
