But in every article I also have this problems (checkin with the Page Speed):
Serve scaled images
Sometimes you may want to display the same image in various sizes, so you will serve a single image resource and use HTML or CSS in the containing page to scale it. For example, you may have a 10 x 10 thumbnail version of a larger 250 x 250 image, and rather than forcing the user to download two separate files, you use markup to resize the thumbnail version. This makes sense if the actual image size matches at least one — the largest — of the instances in the page, in this case 250 x 250 pixels. However, if you serve an image that is larger than the dimensions used in all of the markup instances, you are sending unnecessary bytes over the wire. You should use an image editor to scale images to match the largest size needed in your page, and make sure that you specify those dimensions in the page as well.
Defer parsing of JavaScript
In order to load a page, the browser must parse the contents of all <script> tags, which adds additional time to the page load. By minimizing the amount of JavaScript needed to render the page, and deferring parsing of unneeded JavaScript until it needs to be executed, you can reduce the initial load time of your page.
Minimize redirects
Minimizing HTTP redirects from one URL to another cuts out additional RTTs and wait time for users.
Those are the errors and Id like to solve them, because more than ten seconds is too much. I don't know if they are because of the template or Joomla, but Im trying with compressing plugins and extensions and they don't solve this issues. The worst one is with the images, I get a low mark in Page Speed (61/100) especially because of that.
I've got every CSS compression option and Cache ON, and I've got also the plugin JCH Optimize. I use a VPS server with Litespeed but its pointless if the website is still slow.

Thank you!
