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

something special being written for linux on GIT code ?

On Linux (and any platform that supports pthreads), Git will do the
lstat() operations to refresh the index in parallel. See the
core.preloadIndex option (which I think defaults to true).

If you have a very high-latency lstat() and your build does not have
pthread support, that could be a significant difference.

That might be worth exploring.
