Note that it's not just a single AXFR - you need to update your local slave copy whenever the master copy changes.

I suspect the total data transferred via AXFRs will be significantly higher than just caching lookup results. --=20 Peter Jeremy --RASg3xLB4tUQ4RcS Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGnIw0/opHv/APuIcRAquzAJ4w05E9GNV/cOWFHdVksxD3DG05dACgif5/ +RpLSqtSjYZP1D6DXL4bSbs= =BFLf -----END PGP SIGNATURE----- --RASg3xLB4tUQ4RcS--
