I'd be surprised if there wasn't more of a correlation with that than with version number. There have been some memory management fixups, but overall, my impression is that it's largely correlated with the amount of space it takes to hold a few copies of the databases in RAM. --=20 -------------------------------------------------------------------------- | Stephen Gran | Doubt is not a pleasant condition, but | | steve@lobefin.net | certainty is absurd. -- Voltaire | | http://www.lobefin.net/~steve | | -------------------------------------------------------------------------- --4Ckj6UjgE2iN1+kY Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFIeUgMSYIMHOpZA44RAvL6AKDXgkH6n6uIw9br9RJwfi9yP2IsvgCglK0P j71ZmKIZpcU8ebQd7yW5T6E= =Ehg0 -----END PGP SIGNATURE----- --4Ckj6UjgE2iN1+kY-- --===============1882646976== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://www.clamav.net/support/ml --===============1882646976==--
