I would consider a size reduction a success if it doesn't impact performance, although higher speed is always nice.
A lot of my research is currently waiting on the XML node dump patch, since vectorisation would have to be done at the node level to be most efficient. Also, my optimiser overhaul is still pending, so I can't really touch the peephole optimiser until it is either accepted (if it still merges!) or rejected. Gareth aka.
