When doing performance checks, make sure you are using a "release" configuration, and do NOT have a debugger attached. If the JIT optimization is disabled (as it will be in either of the cases) you will get much poorer performance. Remember that it is the JIT which decides what to inline, and is a MAJOR factor in performance.

I use NamedQuery; I runned the same query but picking only value like select a, b, c, so there is no transformation from data to object, and it takes 15ms So, there is a lot of time and CPU to transform the data; Is there a way to optimize this process? perharps I can write something to avoir reflection ? thk -- You received this message because you are subscribed to the Google Groups "nhusers" group.
