Page Speed analyses the performance of web pages and gives specific suggestions for making them faster. Page Speed is available from any browser. This allows website owners to get immediate access to Page Speed performance suggestions so they can make their pages faster.

The suggestions are divided into High, Medium and Low priority. The test, appropriately, runs in a matter of seconds. This site scored well with a grade of 91 out of 100. Here’s what Google suggests should be done to make up the 9 points:

That’s an analysis of desktop page speed; you can select to also run a mobile speed report.

There are also page speed extensions for Firefox and Chrome, as well as other code and instructions for developers on that page.

Websites are increasingly the key communication vehicle for a company, its brand and products. Despite this, research from Magus shows that many of the world’s leading organisations don’t have formal brand and technical standards defined to govern their websites. Even those that do are failing to effectively implement or enforce them, achieving full compliance with less than 20% of their own web standards. The websites of these organisations significantly under-perform or damage the brand as a result.

PAS 124 will help to protect the significant investment organisations are making in their web presence and online brands, by establishing best practice for “defining, implementing and managing organisational web standards”. It will provide a clear framework to help organisations apply standards effectively to significantly improve online performance and protect the integrity of their brands.

Performance refers to the response time of requests to CFML pages and Components (CFCs), whilst scalability refers to how the performance results change when the load on the server increases.

Factors Affecting Performance

• Hardware and software configuration
• Database and other external system requests
• Web server performance
• CFML application
