> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Ayush Saxena
> Assignee: Ayush Saxena
> Priority: Major
>
> The connectionID Hash Code and equals contains ugi.toString(), These methods
> are used as part of getConnection() in ConnectionManager as part of every
> call.
> 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.
