> The connectionPoolID Hash Code and equals contains ugi.toString(), These
> methods are used as part of getConnection() in ConnectionManager as part of

> The ugi.toString() eats up considerable amount of time, the Hash Calculation
> itself is ~10 percent of the total time of the call. And even more for the
> equals method.
