Hi everyone!

JOOMLA 3.8.1 , Virtuemart 3.2.4


My website with vm is too much slow more than any website in this life.

Please check this and help me with something I can do to speed up it.

Tested from servers in UK, US and Australia. Response time of server from first contact is around 23 seconds, index page starts loading at aroun 28-30secs and complete around 34-36secs.   
See https://www.webpagetest.org/result/171021_EK_1ba067f95f2b7b7a481dd3b77cdb80cd/  for an example.

I guess the first place to look is at server performance, then reduce image file sizes, 90% of page load is images.  There is a lot of content for an index page.

index.php/en/shop/category-page.html load in 1.73s
Main page in 23s
First, your framework minify dynamical eg.
YOURSITE/plugins/system/yt/includes/libs/minify/?f=/templates/sj_shoppystore/asset/bootstrap/css/bootstrap.min.css
This is poor, because need each time to compile and load with PHP
try to change Framework(or disable it for test), or perhaps disable minification.
In all case your site has to many JS(22 files) to many css(22 files)
no http2 support for your server > see https://tools.keycdn.com/http2-test for eg.(speed gain 20% minimum)
Your template sj_shoppystore, have no optimised image. You can win 50% size > check google pagespeed
And shop images too.
If you remove your poor home page and optimize all your files, i think you have a standard speed and a correct google pagespeed
