and of course you need to know what ruleset/pre-processors
you are using... I haven't done any serious benchmarking
(all me sensors have a lot of headroom just now).

Anyone have any thoughts as to a "minimal" ruleset - perhaps
<100 rules and concentrating on actual attacks and generic
rules (such as the x86 NOOP rule)?
