performance issue: git clone compression

[Tim Webster]

git clone gitosis@gitserver:code.git

After remote counting objects, remote compressing objects
transfer begins...
This compression operation results in excess of swapage on the remote server.

--------------------

I need to avoiding the clone compression step for servers with limited memory.
I am doing the following to avoid this object compression. Is there a
better way?
-------------------

scp -r gitserver:/srv/gitosis/repositories/code.git  .
git clone /tmp/junk/code.git --no-hardlinks code
# IS there a better way of converting the bare git repository to
working git repository?

edit .git/config
url = gitosis@gitserver:code.git

Make sure the remote repository is fully packed.  To do so, just go into
the remote repository and run 'git gc'.

On servers with limit memory it is not piratical to run git gc.
I can run git gc on a bare mirror and rsync back to the server.

I would prefer to for go compress packing entirely for the large git
repositories containing media files.

Can I disable compression by file attribute via .gitattributes?

I am trying to use git for all repositories to avoid a mix of version
control methods.
For media repositories I am using

[core]
    repositoryformatversion = 0
    filemode = false
    bare = false
    logallrefupdates = true
    compression = 0
    loosecompression = 0

[pack]
    # disable delta-based packing
    depth = 1
    # disable compression
    compression = 0

There is no problem with git pull and push
Just git clone swaps the server to death

That is fine.  As long as you end up with a single pack, then a clone
would basically be a sinple file transfer.

Also you might want to investigate the following config variable for a
low-memory server:

        core.packedGitWindowSize
        core.packedGitLimit
        pack.windowMemory
        pack.deltaCacheSize
        pack.deltaCacheLimit
