Hey Arturo,

First and foremost, you need to use a reputable page speed testing tool like the Google PageSpeed Insights tool located here:

https://developers.google.com/speed/pagespeed/insights

Secondly, make your way over to my recent blog post on our new SiteSpeed platform. If you leave a comment in the comment area on my post, you will be entered into the BETA program and you will have the ability to toggle SiteSpeed ON for your website. This will give you a much faster website.

However, you will still have issues with images being large, so you'll want to install and run the EWWW image optimizer plugin to help optimize your images for the web.

Here is my post: SiteSpeed - Taking WordPress Website Speed into Unchartered Territory! Carson

wow arturo - as has been said below your page size is huge
one page i have just produced >5k words with 30 odd pictures is only 1mb complete
gt metrix is complaining about the image size - but i know they are relatively small
i don't like to rely on plugins for this and reduce the size of the images myself
as carson said ask for site speed and you will be allowed to beta test it
good luck getting the speed up and the size down

Arturo, I hope your speed will improve soon!

This immediately looks like an "image" problem, you an see that the top of your results there show your images are causing the issues. They are huge, they are slowing down your site.

If you don't already have it, you should get EWWW Image Optimizer (plugin) and perform a Mass Optimization on your site. This will improve this drastically.
