What do you mean by this: "AJAX compared with tailor-made codes"

Performance wise with Ajax is based on: Type of conection user is on (T1,dialup,DSL,etc), where they are located compared to the server, type of caching involved (client and server), the business logic on the server (how long is it going to chug to get the data out), and how well the client side code is implemented.
An Ajax script may look like lightening fast testing, but the developer needs to realize that there will be traffic on the net and not everyone has a direct connection to the server.
