Re: serious performance issues with images, audio files, and other "non-code" data

We're seeing serious performance issues with repos that store media
files, even relatively small files. For example, a web site with less
than 100 MB of images can take minutes to commit, push, or pull when
images have changed.

Our first guess was that git is repeatedly attempting to
compress/decompress data that had already been compressed. We tried
these configuration settings (shooting in the dark) to no avail:

    core.compression 0   ## Docs say this disables compression. Didn't seem to work.
    pack.depth 1     ## Unclear what this does.
    pack.window 0    ## No idea what this does.
    gc.auto 0        ## We hope this disables automatic packing.

Our guess that re-compression is to blame may not even be valid since
we can manually re-compress these files in seconds, not minutes.

Is there a trick to getting git to simply "copy files as is"?  In
other words, don't attempt to compress them, don't attempt to "diff"
them, just store/copy/transfer the files as-is?

Search for `delta` attribute, which should be unset for files that you
don't want for git to attempt (binary) delta against, in gitattributes
manpage.

P.S. There is also git-bigfiles project that migth be of interest to
you.
