A lot depends on how you're using the objects and / or data. CF is very good at caching database queries so re-running the query is not a big overhead (because, well, basically you don't end up re-running the query!). > This would give us easy access to the objects...I thought that, with > ColdFusion, structures were essentially Hashtables. And, CFCs were > essentially objects. So I figured this would be a "slam dunk". CF provides quite a thick abstraction layer over Java so while some idioms translate over well, others do not. CFCs are objects but, for example, a method is *also* an object so that CF's 'late binding' and metadata model can behave consistently. Furthermore, CF's structs are case-insensitive which adds overhead compared to Java's hash tables. > Is there another way you would suggest, just speaking in general OO > terms even, that would speed up this problem?

I don't have enough information to hand to say whether the design is or is not appropriate to the problem you're trying to solve. If you could tell us a little bit more about how you are using the data / objects and what the application does, that would help.
