[SOLVED] HTTPMethod in Synapse is slow and freezes program operation momentarily

Hi,

I have installed Apache2 server on my computer (OS: Ubuntu 10.04), with PHP and MySqlite support.

I am using this function below to send HTTP post method to a PHP file (that resides in a site also in my computer), I am using synapse library.

--- Code: ---function PostInetCommand(cPostData:string):string;
var
  HTTP: THTTPSend;
  l: tstringlist;
  cResponse:string;
  b:boolean;
begin
  HTTP := THTTPSend.Create;
  l := TStringList.Create;

  try
   if not HTTP.HTTPMethod('POST',cPostData) then
   begin
   Result:= 'Error';
   end
   else
   begin
   l.loadfromstream(Http.Document);
   Result:= l.Text;
   end;
  finally
   HTTP.Free;
   l.free;
  end;
end;

--- End code ---

I find that the program operation freezes momentarily and the response from PHP file is very slow (at least 3 -4 seconds), whereas the same post operation done from a browser is instantaneous.

Please explain why this is happening ?? also how can I improve the performance.

PS: Sorry if I could not make myself clear as I am new to network programming.

thanks
nm

Mine here is fast, could you make sure that it's faster with php?
