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.
CR 6378256 seems to cover this for the client/C1 compiler. Presumably
the server/C2 compiler already intrinsifies the method. It's been in
"fix understood" for a couple of years...
