Question by DOLLFACE: How do I minimize DNS lookups with Page Speed?
I’m using a Firefox add-on called Page Speed by Google. It’s supposed to speed up my website, but when I expand the suggestions after analyzing my blog, I don’t understand the jargon.
This is what it says:
Serve the following JavaScript resources from the same host as the main document (creolesugar.blogspot.com), or defer loading of these resources if possible:
* http://code.jquery.com/jquery-latest.js
* /friendconnect/script/friendconnect.js
The following domains only serve one resource each. If possible, avoid the extra DNS lookups by serving these resources from existing domains.
* code.jquery.com
* linkwithin.lg1x6z.simplecdn.net
* www.friendconnect.gmodules.com
* wau.tynt.com
* i676.photobucket.com

So what it is saying is this: that long list of stuff would be served faster if it were all on one server.
Every resource located at a different server has to have its name resolved, this takes time.
If it were all on one server, then there would only be one name resolution to do.
So for instance, I see at least four different image servers in your list, one optimization could be to place all images on *one* of the servers — in this way, you just eliminated three DNS lookups.
Carry this principle with all of your other content and page loading speed will increase, as far as DNS lookups go.
Hope this helps. Oh, I lol’d a little when I read “creolesugar”
