Is it faster to transmit the file while the filename is renamed to dump_gitlab_backup.tar?

How to Use GitLab Self-managed

This page (Back up and restore GitLab | GitLab) mentions:

Users of GitLab 12.1 and earlier should use the command gitlab-rake gitlab:backup:create instead.

The resulting file is named dump_gitlab_backup.tar. This is useful for systems that make use of rsync and incremental backups, and results in considerably faster transfer speeds.

Does someone know why the shorter filename can lead to the transmission speed faster?

I think the comment is tied to the code block before which uses a different syntax. Comparing them as follows:

# current
sudo gitlab-backup create BACKUP=dump 

# < 12.1
sudo gitlab-rake gitlab:backup:create
