Load First Parse Later
The Google GMail Team came up with this one for solving latency issues on mobile based apps:

This one speeds the loading of a mobile web page + full parsing of the interaction layer(Javascript) from 2600ms to 240ms (10 faster!!) on the same script block size(200KB)!!
Worth trying when customising web apps for moblies (which has good 3G bandwidth but really bad latency due to the transport over microwave).
