Can a Novice Fix Parallelize Issues?

[Anita_Clark]

I was working yesterday on making my WP site quicker (sellingwarnerrobins.com) and after updating the htaccess file to solve some "Leverage Browser Caching" issues I re-ran a scan on Pingdom Tools and am now getting a zero for "Parallelize downloads across hostnames" with a list of 34 items to fix.

I did some web searches and when the articles started talking about cnames, subdomains, and hostname distribution it went beyond my capabilities.

Are these Parallelize "issues" something a novice like myself can easily fix?  If so, how?

From my understanding a browser can only download a certain number of elements from one domain at a time. So if your site has 100+ elements some are queued while downloading the current ones. By using parallel domains (a sub domain or a CDN Content distribution network such as amazon s3) the browser can download from several at the same time saving a small amount of download times.

http://www.cloudflare.com/features-cdn is the easiest to set up and is effectively free however there are always minor drawbacks to any system.

You can host images on a subdomain to help and use a plugin like w3 total cache for wordpress to do caching and cdn however I can't say I went so far as to go down this route.

Very few websites need to parallelize and pingdom tools offer it as a suggestion. If your page speeds are good you don't really need it and the time/effort it will take to set up.

Hopefully someone else can chip in here and fill in the blanks.

Thanks for the input Brian.  I am afraid of messing something up and being unable to correct it so will do nothing until/if I know what needs to be done (or pay someone to accomplish).

I do want my site to be faster but if this is only going to be a marginal improvement (if at all) I am not sure the increase outweighs the headache/cost.

I am still trying to wrap my brain around this techie "stuff"...way more of the elephant than I can chew at the moment.  

BTW...What I failed to mention above is my site is currently hosted at GoDaddy.  Not sure if that has any relevance or not.

I find it a little confusing too, I run a mangento store so it might a little different.

My ISP says to create pointer domains on the same server.

Such as:
http://www.mysite.com/
http://images.mysite.com/images/
http://js.mysite.com/js/http://media.mysite.com/media/
