Hi,
I have full clone of Vim repository [1] on my computer. This repo has
tags for each commit, meaning that when there is a new commit landed on
default (master) branch, it will be tagged (something close to release
tags but not same).
While on the other repo, doing git fetch will fetch new commits from the
remote quickly (the only limit is network bandwidth), on vim repo it
takes longer.
Examining the trace (run by `GIT_TRACE=1 git fetch`), I got:

git fetch took about 100 seconds to complete, including fetching 3 new
tags. On the other repo, the same command took around 10-20 seconds,
depending on how large data that must be downloaded.
Note that Vim repo has 13952 commits and 12284 tags; and for testing
above I use Git 2.31.1.
Thanks.

I sometimes work on that repo and I just have to say how much of a
pleasure it is to work on a properly maintained repo such as git.git.
My last bisection on vim.git landed on this beauty of a commit:

What were you doing there? I'm discussing about performance issue instead.
