You might want to consider setting a lower vfs.zfs.arc_max in /boot/loader.conf The default is all memory less 1GB, or 95% of memory, whichever is more, and this is likely too high for your usage case. It is infact too high for every use case except a server that does nothing but act as a file server. --=20 Allan Jude --dVenEAlPaiWfNH5xGXKNGlerqc2Qs36Et Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.16 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJTh0bDAAoJEJrBFpNRJZKfgtYP/RfyoLMesoZ8tOhCYq2naDaY ZsQJmN+NRRvUwkEAt/ImzygUj80Ls0BTxZxLLcJN1G5B3ApXTLUVGpB5gSoiVY8c jsarcLHdKPlSr54BJE0bHnKU+MdvP6gk/4I2qUjETPUNrMigVkFB+QdacYrF6NIT AnFq+jw+sGx9FrcyvhP8IiBlc0OfUqxcVscPoX3yFjyptoV0fTL0Ef+6AmOe+YAr I9MRk72Bh3UNovwJTqKyBhxS4LK+O9vT6drE8z4C7Eb6t2FVM4RlGM8ry0h9tEeA 3H91iId6IPRathd5k8RelqjDqew+QpXhq/7G4fGEKoS9mTQIJbOP6eiEmv+bVuQz A1uYAUvOhHsGh/mLAz/U0VchkWk5oE3e0GEoYVCT5WmPkQvUOWZesdt7huMayIKl il9kuKykNyyujNK/OB4E3E/mddY4vy1rJ52a9vT55eO5KgOtQ+M2lwyW2BkcPZ/s JKKryDrn3r+UHUyorlQWJsZZ+/ySy7VB0wfccCeHFY/leyWLfnZCgBTM5XkjSqyu S+S/HQua7rZ4+/0ToHHLlHi4tRLg2g6U/gtVGijw5qqaYk2+tWh8sYNGReVQVjpL oPZpcMXwA+8S0GpC2yR8yuw49Wv0T8ERePbD+ux3iEmwqHytyVyYXBHNMl9fqYHh kcNNXThK631TbQxgkqVE =t4Eq -----END PGP SIGNATURE----- --dVenEAlPaiWfNH5xGXKNGlerqc2Qs36Et--
