Hi all

I test my Site speed by google tools. please look at this:

 http://developers.google.com/speed/pagespeed/insights/?url=http%3A%2F%2Fbyterry.ir%2F%25D8%25A2%25D9%2586-%25DA%2586%25D9%2587-%25D8%25A8%25D8%25A7%25DB%258C%25D8%25AF-%25D8%25AF%25D8%25A7%25D8%25B4%25D8%25AA&tab=desktop

I use, Optimize and good Skin from bestdnnskins.com, thay have very good quality skins and I use it for this site. I test it and for desktop I have 75% from 100%. there is 2 big problem:

1.

Reduce server response time

In our test, your server responded in 1.6 seconds. There are many factors that can slow down your server response time.

2.

Eliminate render-blocking JavaScript and CSS in above-the-fold content

 How can I Fix second Problem on DNN 7.3.1? I want block loading som JS and CSS. any body can help me about that?

Regarding the jquery message you can't make any change - google already explicitly acknowledge this at https://developers.google.com/speed/d... i.e.

What if I am using a JavaScript library such as jQuery?

Many JavaScript libraries, such as JQuery, are used to enhance the page to add additional interactivity, animations, and other effects. However, many of these behaviors can be safely added after the above-the-fold content is rendered. Investigate making such JavaScript asynchronous or defer its loading.

 

As there is no way to know if a loading module requires jquery functionality before the page is loaded, then there is no safe way to defer loading

There is control. It is the responsibility of the module to say if it needs jQuery. If one, or more, modules on the page want it then DNN loads it once. If no module wants it DNN does not load it.

Secondly; get jQuery from a CDN. Then the long duration cache header will mean that the cached copy is used every time after the first page that needs it.
