Azcopy is consuming more time than usual for incremental sync azcopy_linux_amd64_10.23.0

[challaswamy097]

Which version of the AzCopy was used? 10.23.0

Note: The version is visible when running AzCopy without any argument

Which platform are you using? Linux

What command did you run? time /conf/share/ms-azure/azcopy_linux_amd64_10.23.0/azcopy sync --recursive --delete-destination=true --log-level=ERROR /conf/homebackup29feb24/confluence/attachments/ "https://xxx.windows.net/confprodnfs/shared-home/attachments/$SASTOKEN"

Note: Please remove the SAS to avoid exposing your credentials. If you cannot remember the exact command, please retrieve it from the beginning of the log file.

What problem was encountered?

Once we run the command we see the below output
3386290 Files Scanned at Source, 3374267 Files Scanned at Destination, 2-sec Throughput (Mb/s): 0

Later after some time, it shows below
0.0 %, 13455 Done, 0 Failed, 6476766 Pending, 6490221 Total, 2-sec Throughput (Mb/s): 0

How come 3386290 became 6490221 for incremental sync. We have an 8GB difference for source and destination but the time consumption is more than expected this didn't happen in earlier versions of Azcopy.

How can we reproduce the problem in the simplest way?

Just do an incremental sync, and you will notice this issue.

Have you found a mitigation/solution? No
