/rest/api/2/status REST request performance

Fire a REST request /rest/api/2/status to the JIRA instance would takes up a minimum of 1.5 minutes or sometimes even more than 2 mintues. It seems that JIRA is locating all the active status which associate to the workflow and workflow schemes.

The problem seems to occur when you have a really large list of workflows and workflow schemes association. The request spending 99% of the time on waiting the request to be completed in order to retrieve 70++ statuses from the JIRA instance as we can see in the following screenshot:

More result from JProfiler attached and a sample HAR file attached for further review.
