JIRA Performance is bad to get deleted worklogs

Summary

When the customer request to get worklogs using REST API calls, the application timeouts due to its performance.

In both cases, the users are trying to get deleted worklogs using this endpoint:
/rest/api/2/worklog/deleted?since=timestamp

However, in both cases, it's failing with HTTP/1.1 504 Gateway Time-out.

Our natural suspicion is that for both cases, there were too many worklogs retrieved, causing a timeout.

Environment

JIRA v1000.789.5

Steps to Reproduce

1. Try to access this in a browser after logging in (or use curl to do a GET request):
