Considering ample computer resources
Note that for the most part, using the unbound session-free, and especially the session-free application model, makes the best sense when you must provide high throughput with minimal computing resources. On the other hand, if you only have minimal context that needs to be maintained between requests, and you have plenty of computing resources relative to your current and expected client load, there is no inherent advantage to using the session-free, or even the unbound sesssion-managed model. Under these more favorable conditions, even if there is only minimal context to manage, using the session-managed model in a bound connection might provide a somewhat simpler programming model.
