Why does Cygwin always use absolute paths instead of
OBJECT_ATTRIBUTES.RootDirectory in NtOpenFile(),
NtSetInformationFile() for rename and hardlinks
This slows down Cygwin path lookups a lot, and with lots of path
elements each lookup with a relative RootDirectory might be a lot
faster, e.g. for openat(), linkat(), renameat().
Because volunteers' spare time is limited, and performance is good enough for
those who might do the work:
