Rule efficiency

["Isherwood, Jeffrey - IS" <Jeffrey.Isherwood () itt com>]

I'm on the lookout for some traffic to several domains that I have been asked to monitor... and I'm wondering which is 
more efficient, several rules that each only look for a domain name - or one rule that looks for many domain names at 
once?

Currently I'm doing the one at a time method, but the list of domains I need to monitor just quadrupled and I am unsure 
which would be more efficient...

Examples:
alert tcp any any -> any any (content:"baddomain.com"; nocase; priority:1; msg:"suspicious domain traffic alert 
baddomain.com "; classtype:string-detect; sid:1000422; gid:1; rev:1; )

alert tcp any any -> any any (content:"crappydomain.com"; nocase; priority:1; msg:"suspicious domain traffic alert 
crappydomain.com"; classtype:string-detect; sid:1000340; gid:1; rev:1; )

alert tcp any any -> any any (content:" shoulndtubworking.com "; nocase; priority:1; msg:"suspicious domain traffic 
alert shoulndtubworking.com"; classtype:string-detect; sid:1000420; gid:1; rev:1; )

alert tcp any any -> any any (content:"wasteoftime.net"; nocase; priority:1; msg:"suspicious domain traffic alert 
wasteoftime.net"; classtype:string-detect; sid:1000409; gid:1; rev:1; )
