How to resolve these issues?

[Mark_Zuckerberg]

Hi all i want to learn how to do resolve these issues in vbulletin


1.) Add Expires headers
example
http://widgets.digg.com/css/buttons3.css
http://platform.twitter.com/js/xd/jsonrpc.js
http://platform.twitter.com/js/xd/parent.js
http://s7.addthis.com/js/250/plugin.sharecounter.js
http://www.google-analytics.com/ga.js

2). Make fewer HTTP requests
example
This page has 30 external Javascript scripts. Try combining them into one.
This page has 7 external stylesheets. Try combining them into one.
This page has 17 external background images. Try combining them with CSS sprites.


3.) Compress components with gzip
my gzip is on at level 9

4.) Use a Content Delivery Network (CDN)

5.) Use cookie-free domains

6.) Reduce DNS lookups
example
s7.addthis.com
widgets.digg.com
api-public.addthis.com
ssl.gstatic.com
platform.twitter.com
www.google-analytics.com
platform.linkedin.com
apis.google.com
connect.facebook.net
www.stumbleupon.com
www.statcounter.com

7.) Specify image dimensions

8.) Leverage browser caching

9.) Specify image dimensions

10.) Parallelize downloads across hostnames
