I'm not sure any of this is relating to the pack structure. Git is spending most of its time writing the large number of large files into the working directory - it is stress mostly the disk, with a bit on the CPU (neither is acceptable to the customer). I am really unsure there is any way to make things better. The core issue is that the customer insists on doing a clone for every feature branch instead of using pull/checkout. I have been unable to change their mind - to this point anyway. We are going to be setting up a detailed performance analysis that may lead to some data the git team can use. Regards, Randall
