git pull without remotely compressing objects

Question

I have a repository full of zip files, re-compressing theses files will be a waste of time.

I've tried to set core.compression = 0 on the remote and the local copy without success

git config core.compression 0 git config core.loosecompression 0 

git pull still do

remote: Counting objects: 23, done. remote: Compressing objects: ... 

Answer 1

The time problem I had was caused by delta compression.

The solution for me was

echo '*.zip -delta' > .gitattributes git gc 

I will quote this excellent response from Re: serious performance issues with images, audio files, and other "non-code" data:

Git does spend a fair bit of time in zlib for some workloads, but it should not create problems on the order of minutes.

For pushing and pulling, you're probably seeing delta compression, which can be slow for large files

 core.compression 0   # Didn't seem to work. 

That should disable zlib compression of loose objects and objects within packfiles. It can save a little time for objects which won't compress, but you will lose the size benefits for any text files.

But it won't turn off delta compression, which is what the "compressing..." phase during push and pull is doing. And which is much more likely the cause of slowness.

 pack.window 0 

It sets the number of other objects git will consider when doing delta compression. Setting it low should improve your push/pull times. But you will lose the substantial benefit of delta-compression of your non-image files (and git's meta objects). So the "-delta" option above for specific files is a much better solution.

 echo '*.jpg -delta' >> .gitattributes 

Also, consider repacking your repository, which will generate a packfile that will be re-used during push and pull.

Note that the settings have to be made on the repo you are fetching/pulling from, not the one you are fetching/pulling to.
