JavaScript Tutorial – How to reduce loading time
Introduction: this script was designed and tested with different browser: “Firefox, IE7, IE8 and Google Chrome.”
This Javascript engine allows the server to load all javascript in parallel mode without reducing your servers’ performances. After that, it will cache all of your script, so that the server will not upload it again! However, this javascript requires: “Java Runtime Environment.” The application can be found here: http://filehippo.com/download_java_runtime/
