Issue/Introduction

• Syncing an empty bucket takes more than 5 minutes in VMware Cloud Director (VCD) Object Storage Extension (OSE).
• Storage vendor is integrated with Object Storage Interoperability Service (OSIS).
• The sync and async start and end task can be seen in the /opt/vmware/voss/log/ose-default.log also 5 minutes apart with debug logging enabled:
