System.identityHashCode performance

[Janda Martin]

I would like to ask about any plans of speed improvements to "System.identityHashCode" or "IdentityHashMap"

I use EclipseLink and it uses IdentityHashMap for storing entities and their clones.

In my case System.identityHashCode consumes 54% of time during insert data to database. There are lots of other project using IdentityHashMap and identityHashCode.

Thank you very much
