I have an application which is using JPA and hibernate as its entity manager.
I see that the performance of the application is good on Websphere which is installed on windows.
But the performance is slow on Websphere which is installed on Solaris.

After spending few hours on our performance problem, we see that hibernate query execution and data binding is taking lot of time on Solaris when compared with Windows. Here the hibernate query that I am mentioning returns 1500 records. On windows hibernate is taking around 340 ms, where as in Solaris it is around 1700 ms.

Is this normal behavior of hibernate?
Please do let me know if I have to add any other information
