RE: Application vs. Applets vs. Servlets

[rstearns@xxxxxxxxx]

Actually the servlet can be quite a  bit faster then the applet for a couple
reasons. 1) Once started a servlet isn't stopped and started with each request
and the servlet can actually be pre-started with the server.  2) No class
download is required to the client since everything is resident on the server.
3) The only thing running on the client browser is HTML (pretty fast).

I guess the simple answer is that if you do all your business logic in
the applet (no back-end logic), then the applet has to access the data-
bases over the network.  This alone can cost you an arm and a leg in
terms of performance.  Other than that applets in the real world will
usually perform better than Java on the '400, because you have much
more CPU power on your desktop than the portion you get out of your
server.
