What app is this ? Considering the above code is a wrapper for stat() fstat() lstat() syscalls= and you only seen a small decrease I would believe its using something els= e quite intensively but without the application at hand or at least a ktrac= e(1) or a truss(1) of the running proccess, I don't think there is much tha= t can be done. It would be nice if something like this was natively available but we tend = to lack a few things here in FreeBSD that can be seen elsewhere. --HlL+5n6rz5pIUxbD Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJOzlngAAoJEJBXh4mJ2FR+jXMH/3wznogcLe2YAv0VbSfbBccS 8f3/K/OkJWB8AyC49YSy8jDTJe4xxAt75YDY/bmgSFI95cUVCi+dvM382IMjcvxP 48xl6D6EDUXX04Y+I5xmywXw2l4lME3a38sY1T7XRb5DSTxqd5qytWPlLbdxso6m iIQaCv0KorJK+GMj/nXRVqMa8TvoNidt6Q02On93K0eKK3UJCtskTjh1GNOawB5g NTjhm7bkUeMJCk0MY3f/FCrQBVmgX45OJxtf7FdXrWMkIyywml+Fki4EsQK23EG7 +03NUN0gEbTgAt+CriUD1biOwSqbCwLxFCbzyfueakuG2Jz3nPh7tb9xbW1V3ig= =kdNH -----END PGP SIGNATURE----- --HlL+5n6rz5pIUxbD--
