 There’s been a lot of emphasis on DNS performance lately because faster DNS contributes directly to a better user experience.  There’s an interesting flipside to DNS performance though, higher performance DNS servers may be better targets for cache poisoning attacks.  Faster servers give attackers more opportunities to insert fake entries into the DNS – speed can kill (or at least inflict a nasty wound!) so it’s important to understand the security implications if you’re looking to upgrade DNS performance.
