Good question. You need to identify from where this delay in fetching the HTML
page comes. There is many candidates:

  * Proxy authentication
  * The smartfilter patch to Squid
  * The origin server
  * Networking
  * Squid

From what is seen in this log your problem is not that "a long time to have
the answer and suddenly the whole page is displayed in one", but that it
takes a extremely long time for the HTML to be downloaded but not much time
at all for the inlined objects.

A good start would be to make some packet dumps of the traffic between Squid
and the server. This will allow you to tell if the problem is caused locally
in any of the components making up your Squid server, or remotely by network
or origin server.
