It is not a matter of speed only, but mostly memory. For large text concatenations Streams are more memory efficient because you don't create intermediate strings. E.g. 'string1', 'string2', 'string3' ... , "stringN" will require the creation of N intermediate String instances. aStream nextPutAll: 'string1'; nextPutAll: 'string2'; nextPutAll: 'string3'; nextPutAll: 'stringN' Will only add contents to the Stream collection.
