Using Hummingbird to Resolve Pingdom C Rating

Hi.

I ran an optimization Test at:

Note: I am running Hummingbird. I am wondering how Hummingbird can be better utilized to reduce the problem points reported below:

I get these issues:

Grade Suggestion

F0 Make fewer HTTP requests

Decreasing the number of components on a page reduces the number of HTTP requests required to render the page, resulting in faster page loads. Some ways to reduce the number of components include: combine files, combine multiple scripts into one script, combine multiple CSS files into one style sheet, and use CSS Sprites and image maps.

F0 Use cookie-free domains

When the browser requests a static image and sends cookies with the request, the server ignores the cookies. These cookies are unnecessary network traffic. To workaround this problem, make sure that static components are requested with cookie-free requests by creating a subdomain and hosting them there.

F0 Add Expires headers

Web pages are becoming increasingly complex with more scripts, style sheets, images, and Flash on them. A first-time visit to a page may require several HTTP requests to load all the components. By using Expires headers these components become cacheable, which avoids unnecessary HTTP requests on subsequent page views. Expires headers are most often associated with images, but they can and should be used on all page components including scripts, style sheets, and Flash.

E60 Reduce DNS lookups

The Domain Name System (DNS) maps hostnames to IP addresses, just like phonebooks map people’s names to their phone numbers. When you type URL http://www.yahoo.com into the browser, the browser contacts a DNS resolver that returns the server’s IP address. DNS has a cost; typically it takes 20 to 120 milliseconds for it to look up the IP address for a hostname. The browser cannot download anything from the host until the lookup completes.
