This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enigD1EAE3A11987E836AF0EBEAF Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: quoted-printable Johan Hendriks wrote: > now i have installed 7.0rc1 amd64 version on a quad core xeon and updat= ed yesterday my src and did a buildworld cycle > On this machine i am running the same jails 1 for proxy and one for the= mailscanning. > but if i do i top here i see much higher values of size used > this is my first amd64 install, the 6.2 is a i386 install There are two reasons for the behaviour you noticed: a) 64-bit software takes more memory than 32-bit, by definition=20 (pointers are twice the size, etc.) b) The memory allocator (malloc) was completely changed in 7.0, and it=20 requests more memory from the kernel than the one used before (don't=20 worry: the amount of memory actually _used_ has nothing to do with how=20 much virtual memory is allocated). In your case, these two factors have increased memory usage from 82 MB=20 to 110 MB, and allocation from 92 MB to 141 MB. There's nothing bad=20 here, if you have enough memory. --------------enigD1EAE3A11987E836AF0EBEAF Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHl9SoldnAQVacBcgRAhKWAJ90vdt2jEXub5UPPqm0zMVXqyGcaQCePmYE t3WIIilXEtRBUVflsmKMXuQ= =CYUE -----END PGP SIGNATURE----- --------------enigD1EAE3A11987E836AF0EBEAF--
