One area where WPO needs more standardization is performance analysis. There are numerous performance analysis tools available, including Page Speed, YSlow, AOL Pagetest, MSFast, VRTA, and neXpert. There’s some commonality across these tools, but the differences are what’s noticeable. To get a thorough performance scrubbing, web developers have no choice but to run multiple tools and sift through the different results trying to find the most important recommendations. It would be better for developers to have a more standard way of analyzing performance across environments. The Page Speed SDK provides a path to achieve this.
