Since we launched Ubiquity 0.5, the issue of Parser 2 performance has been brought up over and over within the community. By virtue of having a more flexible and localizable design, Parser 2 was expected to be slower than our original parser, but its current implementation felt noticeably—perhaps unnecessarily—slow compared to Parser 1. Parser 2 performance has been identified as one of the blockers for pushing Ubiquity 0.5+ to all of our 0.1.x users, and has thus been one of my recent foci.

The short story:

Inspired by some comments by Blair, yesterday I was able to make significant (roughly 100%) performance gains in Parser 2, resulting in 40-60% faster parses, depending on the query. This change has been committed and will be released as part of our forthcoming minor update, Ubiquity 0.5.4. Yay!
