Hi levente we are performing a study with veronica and we looked at Monticello-ul.331 in squeak trunk you mentioned that name hashWithInitialHash: 0. is faster than String stringHash: name initialHash: 0. and I was wondering if this is true and why? String hashWithInitialHash: initialHash ^ self class stringHash: self initialHash: initialHash hash | hash | hash := name hashWithInitialHash: 0. hash := superclassName hashWithInitialHash: hash. hash := self traitCompositionString hashWithInitialHash: hash. hash := self classTraitComposition asString hashWithInitialHash: hash. hash := (category ifNil: ['']) hashWithInitialHash: hash. hash := type hashWithInitialHash: hash. variables do: [ :v | hash := v name hashWithInitialHash: hash ]. ^hash => hash | hash | hash := String stringHash: name initialHash: 0. hash := String stringHash: superclassName initialHash: hash. hash := String stringHash: self traitCompositionString initialHash: hash. hash := String stringHash: self classTraitComposition asString initialHash: hash. hash := String stringHash: (category ifNil: ['']) initialHash: hash. hash := String stringHash: type initialHash: hash. variables do: [ :v | hash := String stringHash: v name initialHash: hash. ]. ^ hash Thanks in advance Stef and Veronica
