Not sure if there were many details reported, but if this is doing
POST-s,
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
that
fails. These are rather conservative values but can be changed by using
these
functions. The second try value must be larger (or equal) to the first
try
value and the first try value must be larger than 20 ms."
