Compiling a list of popular performance tools here...

No no... I am not talking about an electric saw... for now just limited to web performance tools.

• Closure Compiler  - This is a java app that compiles from JavaScript to better JavaScript so that it can be downloaded faster and run faster. Web version can be found here. 
• Add async attribute can be added to the script tag so that  javascript parsing can be put off so that the web page can be rendered faster.
