Update: Nice explanation in The importance of bandwidth versus latency of how long latencies cause cascading delays in resource loading. Doloto tries to optimize how resources are loaded.

Twenty new rules have been added to the original 14 rules for sizzling web performance. Part of scalability is worrying about performance too. The front-end is where 80-90% of end-user response time is spent and following these best practices improved the performance of Yahoo! properties by 25-50%.
