[rules-users] Rete diagram legend - what do all the colors me an?...

[Mark Proctor]

not really, all I can say is try and work with flat models and '==' 
operators for performance - we currently don't optimise != or number 
ranges. Avoid eval, predicate and return value unless you really need 
them. Keep your consequences short and avoid flow logic in them, i.e. 
'if'/'switch ' statements.
