Hi, Jeff,
   HTTP_setBodyWriteDelay(25, 30) does improve the response from the server.
It cuts the response time to less a second. Now my boss is happy. Thanks for
your helps.

Not sure if there were many details reported, but if this is doing
perhaps you are using the default and very long delays with body writes?

I have been using:
HTTP_setBodyWriteDelay (25, 30);

And libwww is extremely response. 

Maybe the delays you are seeing on the order
of 2 seconds is because of the default values, ie from HTTP.h:

"The default wait periods are 2000ms for the first wait and 3000ms if
fails. These are rather conservative values but can be changed by using
functions. The second try value must be larger (or equal) to the first
value and the first try value must be larger than 20 ms."
