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.
