No rush. I'd just like to understand how removing the commit-graph file

$ time git push --dry-run --follow-tags /home/newren/repo-mirror

Is the above test with or without the commit-graph file? Can you run it in the other mode, too? I'd like to see if the "count" value changes when the only difference is the presence of a commit-graph file.
