Hello,

in my application i need to open a website and mess the parse time. at the
moment i use following lines:

   start = GetTickCount();
   try
   {
      HTTP->Tag = 1;
      HTTP->Port = 80;
      HTTP->Get(Website);
      Source = HTTP->Body;
   }
   catch (...)
   {
   }
    diff = GetTickCount()-start;

This works fine. To check if my results are plausible i also display the
parse time on my website. so i found out, that the time my c++ application
determine is always bigger then the parse time, which my website displays.

so i ask me if there is an better way to get the parse time.

does anybody have some advise for me?

Steffan

Yes but you cannot name that a parse time. Whichever parse time
you have in mind. You just messured the time needed for exeuting
a HTTP->Get() and assigning the HTTP->Body to Source.

That is ok. As the webserver needs some time too and transmitting
data takes time.

You did it already ok with your c++ application.

For your 'application' everything is behind HTTP->Get() and
thus out of sight.

Hi,

what is the english name f�r the time i get via get. can i call it loadtime,
because it is the time, the hole website needs to load?

it is possible to get via nmhttp the respons time of a website? my idea is
like:

start = GetTickCount();

HTTP->Get(Website);

void __fastcall TForm1::NMHTTP1HostResolved(TComponent *Sender)
{
   diff = GetTickCount()-start;
}

so, may i get the responstime with help of NMHTTP1HostResolved or
NMHTTP1PacketRecvd.

Don't think so. If one speaks of the loadtime of a webpage -not
of a website-, then that is with a browser in mind. Even if the browser
grabs the page quick than it still needs time to format the page, 
creating all elements for tables and so. Then if there are img tags all
the images have to be requested separately yet. All that adss to the
loadtime.

Again. The only thing you were measuring was the execution time of
HTTP->Get(WebPage);

> so, may i get the responstime with help of NMHTTP1HostResolved 

No because resolving a hostname has nothing to do with contacting
the webserver. Instead DNS servers are contacted. The host can be 
resolved even if the website is not 'in the air'.

Probably. Did you already try and measure it ?
