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--
