Website loading very very slow! How to optimize ?

RE: Website loading very very slow! How to optimize ?
Your repeat view had me wondering so I re-ran the test:

Your REALLY long onLoad times are caused because something is preventing the load event from firing (possibly the live chat widget).

Your first byte times need a lot of work too. At 3 seconds that's already higher than your target (should be well under 1 second). From the looks of it that is going to be a combination of your DNS provider and hosting provider (or app performance). If you make your base HTML cacheable for some period of time then cloudflare can help by delivering your page directly and not hitting your host.

Focus on the grades at the top first - looking at the waterfall there are a lot of basic things that need to get fixed.

GZip compression for your js and css could save you nearly half of the bytes for them: (if you use cloudflare they can take care of this for you as well). If you are using netdna, why are you not serving your static resources from the CDN? They can also do text compression for you if your host won't.

You need to compress your jpeg images with a lower quality setting. It won't be visibly different but it will cut the size of the images in half.

Since you are on Wordpress you should probably see if you can get W3 Total Cache working and use it to help you optimize:
- Turn on page caching to help with your first byte times
- Use it to combine your css and js files together (you have WAY too many loading separately)
- Enable browser caching with a long cache time
- Configure it to serve your static files from your CDN

Those changes should cut the load time by half at least and will reveal other areas that can improve but don't do any other work until you take care of the issues above.
