I’m a skeptic. As an acceleration play, I see the cost of dynamic site acceleration (aka “whole site acceleration”) products — such as Limelight Site, Cotendo, Akamai DSA and WA, and CDNetworks Application Acceleration — far outweighing the benefit.
The three greatest third-party performance culprits — performance-leeching widgets, badly designed ads, and poorly optimized pages — and real-world tips for dealing with them.
It’s not enough to have a fast site. Time after time I see “high performance” sites that make the same mistake: having their most important content load dead last. Here’s a case study from Symantec.com.
In this webinar, Hooman Beheshti analyzes Google’s home page performance using Web Page Test and HTTPWatch, demonstrates how to interpret waterfall charts, and talks about ways to diagnose and isolate common web application performance problems.
Mystified by waterfall charts, or know someone who is? Today I thought it would be a good idea to take a bird’s eye view of a typical performance waterfall – pre- and post-acceleration – that you can take away for your own reference or pass along to anyone you think could benefit from having this information.
