Recently I have gone through google developer tools to perform my site speed test and got a summery replrt with some suggestions to be implemented to improve my site landing speed.

The below are some detials.

To be fixed Immediately

PHP Code:

Leverage browser caching

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

    Leverage browser caching for the following cacheable resources:
        http://www.mydomain.com/forumrunner/detect.js (expiration not specified)
        http://www.mydomain.com/images/buttons/collapse_40b.png (expiration not specified)
        http://www.mydomain.com/images/buttons/lastpost-right.png (expiration not specified)
        http://www.mydomain.com/images/buttons/newbtn_middle.png (expiration not specified)
        http://www.mydomain.com/images/buttons/search.png (expiration not specified)
        http://www.mydomain.com/images/gradients/gradient-grey-down.png (expiration not specified)
        http://www.mydomain.com/images/gradients/gradient-greytowhite.png (expiration not specified)
        http://www.mydomain.com/images/gradients/grey-up.png (expiration not specified)
        http://www.mydomain.com/images/gradients/selected-tab-gradient-with-top-alpha.png (expiration not specified)
        http://www.mydomain.com/images/icons/icon11.png (expiration not specified)
        http://www.mydomain.com/images/icons/icon14.png (expiration not specified)



Eliminate render blocking Java Script and CSS in above -the-fold content
Your page has 7 blocking script resources and 3 blocking CSS resources. This causes a delay in rendering your page.

    None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.
    Remove render-blocking JavaScript:
        http://yui.yahooapis.com/combo?2.9.0/build/yuiloader-dom-event/yuiloader-dom-event.js&2.9.0/build/connection/connection-min.js
        http://www.mydomain.com/clientscript/vbulletin-core.js?v=422
        http://www.mydomain.com/forumrunner/detect.js
        http://www.mydomain.com/clientscript/vbulletin_read_marker.js?v=422
        http://www.mydomain.com/clientscript/vbulletin_md5.js?v=422
    Use asynchronous versions of the following scripts:
        http://pagead2.googlesyndication.com/pagead/show_ads.js
        http://pagead2.googlesyndication.com/pagead/show_ads.js
    Optimize CSS Delivery of the following:
        http://www.mydomain.com/css.php?styleid=48&langid=1&d=1386508444&td=ltr&sheet=bbcode.css,editor.css,popupmenu.css,reset-fonts.css,vbulletin.css,vbulletin-chrome.css,vbulletin-formcontrols.css,
        http://www.mydomain.com/css.php?styleid=48&langid=1&d=1386508444&td=ltr&sheet=forumbits.css,forumhome.css,options.css
        http://www.mydomain.com/css.php?styleid=48&langid=1&d=1386508444&td=ltr&sheet=additional.css 


I need some valuable suggestions on how to fix these errors.

Thanks in advance.
