Hello ALL, I did try GIT_TRACE* environment variables but couldn't isolate the problem. But HPUX Dev team have seen one significance difference, when they were triaging this issue, the ways GIT operations handled by 2 OSs: On linux, around 40 processes are spawned for handling a GIT operation whereas on HPUX only one process manages the operation. Is there something special being written for linux on GIT code ? Can you please have a look into this.
