>             Project: Derby
>          Issue Type: Improvement
>          Components: Store
>    Affects Versions: 10.6.1.0

> Dyre Tjeldvoll posted some results on DERBY-3092 that indicated that some types of load
might cause contention on XactFactory.tranId (a shared long), and suggested that it was replaced
with a java.util.concurrent.atomic.AtomicLong on the platforms that support java.util.concurrent.*.
> I'm splitting this issue out from DERBY-3092 so that the two possible improvements reported
there can be addressed independently.
