As we know, we can periodically run git gc to pack objects under .git/objects.
In the case of a remote central Git repository (bare or not), though, after many pushes, there many files under myproj.git/objects; each commit seems to create a new file there.
How can I pack that many files? (I mean the ones on the remote central bare repository, not on local clone repository.)

The easiest option would be to use a scheduled task in windows or a cron job in Unix to run git gc periodically. This way you don't even need to think about it.
The git gc command is a repository maintenance command. The "gc" stands for garbage collection. Executing git gc is literally telling Git to clean up the mess it's made in the current repository. Garbage collection is a concept that originates from interpreted programming languages which do dynamic memory allocation.
The git gc command is used to maintain a repository. Garbage collection is denoted by “gc.” Git gc is a command that tells Git to clean up the mess it has created in the existing repository. Garbage collection is a concept that comes from dynamic memory allocation in interpreted programming languages.
In order to push a Git branch to remote, you need to execute the “git push” command and specify the remote as well as the branch name to be pushed. If you are not already on the branch that you want to push, you can execute the “git checkout” command to switch to your branch.
The remote repo should be configured to run gc as needed after a commit is made. See the documentation of gc.auto in git-gc and git-config man pages.
However, a remote repo shouldn't need all that much garbage collection, since it will rarely have dangling (unreachable) commits. These usually result from things like branch deletion and rebasing, which typically happen only in local repos.
So gc is needed more for repacking, which is for saving storage space rather than removing actual garbage. The gc.auto variable is sufficient for taking care of this.
