[Bug-wget] Wget wall clock time is very high

[Debopam Bhattacherjee]

Hi,

I try to download a webpage along with it dependencies using the following
command:
wget -p -k -H -e robots=off --header="Accept:
text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"
--user-agent="Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:50.0)
Gecko/20100101 Firefox/50.0" -P test1234 http://www.stanford.edu

The total download time is 1.4 seconds while the wall clock time is 6.8
seconds which is much higher. Chrome, in comparison downloads and renders
everythin in 2-3 seconds.

Why is the wall clock time so high and how can it be reduced?

Thanks!
