blocking - My http request block,what 's wrong? -


enter image description here

i view homepage in chrome, 1 http request, , encounter case.

what 's wrong?

i can see dns not found when happened, it's not bug of server.

so chrome @ moment.

from: https://groups.google.com/forum/?fromgroups=#!topic/speedtracer/mlf_gtvmrd8

the 'blocked' time delta between 'requesttime' , 'starttime'. basically, measure of amount of time between ui thread initiating request network resource , http request bits getting onto wire. in between, there can internal queuing/message passing delay, cache lookup, dns resolution, , tcp connection setup.

among causes mentioned, sounds dns lookup 1 take long. dns lookup succeeded, otherwise whole request have failed. here's 1 possible cause of dns delay: http://www.bigthinka.net/support/web-browsers/google-chrome-slow-dns-resolving.html

if doesn't solve it. try updating question more info dns settings.
