Nice optimization, but keep in mind folks this is the time to make this stuff thriving feature-wise. So I'd rather see us working on things with high end-user impact such as support for nested queries, analyzers, the AP/SPI overhaul etc. etc. All the perf honing can come at another time, IMHO. This is not to say to not do it if it's a quick thing, but let's keep the priorities right.
