You're right - I ran some tests, and Ip::Country::Fast is not just marginally faster, it's up to 10 times faster than doing local DNS lookups: On a relatively low-end machine (Athlon 1.2GHz, 768M RAM): Ip::Country::Fast - 66000 lookups took 8sec, 839000 lookups took 73sec. local DNS lookup (php) - 66000 lookups = 85sec, 839000 lookups took 25min /Per Jessen, Zürich
