I think you omitted the attachment, but in any event, I would say that
this is not normally expected for `git status`.  We'd really need to
know what the command line of those processes is for us to know what
they're for; for instance, you may be triggering maintenance on the
repository, in which case packing a large repository could legitimately
use that much memory.  Similarly, if you're using a file system monitor
process, that could consume a large amount of memory in a large
repository.

I don't personally use Windows, so I'm afraid I can't tell you how to
get that information there.  Once you have it, though, it should be
clearer if that's a reasonable amount of memory to be using given the
size of your repository.
