Hi,

We have seen that though shorts occupy less memory as compared to ints but
when involved any arithmetic operation they are first promoted to 'int'
type  and then casted back to 'short' type so any performance benefits that
could have occurred as a result of less memory are offseted by their
promotion  to int and then contraction back to short.

Milind

Hi,
   I have a doubt in selecting datatype for a container managed field (in
CMP Entity Bean) specifically for INTEGER type.
If we use 'short' instead of 'int' for Container Managed Field (where the
database mapping datatype is short), will it lead to a performance
improvement?

Usually for INTEGER column in Database, we used to declare int in the Bean
Class.
But for Database like Informix, the actual java Datatype mapping for
INTEGER
is short.
In such case, if we use short instead of int, will it lead to performance
improvement? or only it occupies less memory ?


Thanks in Advance,
Sukumar
