Of this, 43% is spent in QNameFactory.create(String) and 19% creating Strings for that lookup.</p> <p>Rework QNameFactory.create() to work on structured data holding namespace/revision/localName without having to concatenate, which will save the string manipulation as well as speeding up hash-based lookup (as component String hashcodes are likely to be pre-computed).</p> CONTROLLER-1897
