Yup, I can definitely acknowledge the poor performance compared to other 
libraries. There have been lots of changes to JavaScript engines over the past 
few years, and unfortunately some of my early trade-off decisions have not been 
able to take advantage of the more recent JS engine optimizations. The next 
major revision will focus on optimizations for Chrome.
