The performance is prolonged and even the percentage information displays wrong. if you see the below provided info it copied 635158 files out of 905800 but still shows 51.3 %

Hi @challaswamy097 , Thank you for reporting this! Could you please describe the issue a bit more. -
Which AzCopy version are you comparing v10.23.0 with?
Is only sync operation compromised or all?
Could you please attach complete logs for the same comparing to older version?
