My site loads really, really slow

What kind of server is it hosted on?

But in addition to having a better server (unsure, was just asking), there are possibly some client-side optimizations that you could have done. Client side means "in the HTML" for our purposes. It also includes all of the JavaScript and images, etc. All of this executes in the browser.

You images gallery plugin, whatever it is, seems to load the slowest. It would take a real professional to take it apart and make it load better though, not something you could do yourself, since you're a novice.

Except for the plugin, the rest of the site actually isn't loading all that slow for me. Is it on a shared server?

You probably need to ask for technical assistance at your host. It's hard for us to answer your question from here. If you're really serious about this site (it looks great by the way), you should probably get some professional assistance to help you with it.

Whatever script is using Alexa is your main problem.

Your markup isn't the most optimal either. Pointless div tags such as:

<div class="thumb-twitter-entry">
<p>By Nick Bellafatto Stating that Cotto fans would come to Madison Square Garden “to watch him [Miguel Cotto] pass the torch,” still undefeated Austin “No Doubt” Trout’s (26-0, 14 KO’s) words would ring true, as the Las Cruces native becomes the third fighter of three from the state of New Mexico behind both Albuquerque’s Bob [...]</p>
</div>

Why is that even in a div when you can apply the style to the <p>? Pointless waste of bandwidth in my opinion.

Lots of different JS files and functions that could be put into 1 file/function = another waste of bandwidth.

Lots of external files being included such as your Facebook page, is it really worth a waste of bandwidth?

The OP has no idea what you are talking about, scottpool2003, as you can see by this:
This is why I said professional assistance.

This .htaccess - gzip and cache your site for faster loading and bandwidth saving >> samaxes will help you to speed up your site.

A dynamic PHP sites (like WordPress-powered sites) are somewhat slower than static sites, but if you're using a good Web host, the difference should be imperceptible.

If you have any extra plugins that you aren't using then try getting rid of those. The site loaded fine for me. Also your store isn't working.

This problem maybe caused my your host.

Use cash and a better host... or better a VPS

You can even try gzipping your site's contents. This compresses the page before it's sent to the client, therefore increases speeds.

ask your hosting company to check this problem for you.. i think too many(heavily traffic) sites on the same server....

You are currently using decent web hosting service and you can stick with them but the problem is about your coding.

Why did you have two share bars in the same page? Just get rid of it and you will notice a massive speed increase because javascript is the most problematic when it comes to performance so get rid of it.

For my location it is loading ok and not really that slow

Here are my suggestions:

-Disable certian plugins you may have installed one by one and see if a possible scripting conflict is causing this

-Remove some clutter from the home page and place them in other pages. The less to load at the start the less time it will take to load

-Image optimization - you can easily get much lower KB files for your websites.

If all that fails then consider looking into either a private server that doesn't have any one to share with or a VPS

You should optimize your image properly in the size and try to use small images to make your site load faster

do a gmetrix report on your site.. it will give you all the load times for the site and the time each component part takes to load.. you can identify the issue fast..
