Slow page loading

[psm]

Dear all,
I have problem with virtuemart slow pages loading. I check my page via pageinsight and I have just 32 points for desktop. 

Speed Index 4,8 s
Time to Interactive 4,7 s

It suggest me to remove Render-Blocking Resources, but I do not know which of them I can disable and how. Can you please help me?

Here you can see results:

Thank you

Might be a slow crowded server (1000+ websites). If I ping the website, the packet loss results are very high: https://viewdns.info/ping/?domain=smartobchod.sk

Also, you have a CNAME entry for your WWW record but the A record associated is not returned with it! This means an extra lookup needs to be performed, unecessarily increasing loading times for your site.

jjk, i tested your tool https://viewdns.info/, the result is not right.
In my case it get me 100% errors excluded canada.
I have a pageload of 500ms in my country, UK 850ms, CANADA 1.1s, hong kong 4s and max 8s.
If i try australian website i have latency > 600ms, for my server i have < 100ms.
This mean that it really depend the network and the distance.

Note that your server do not support http2
See https://tools.keycdn.com/http2-test
Enable http2 can be 3 or 4 time faster(more you have files, more it's faster)

I don't know if this one is better, but the results view looks nice  :

Maybe the live chat is causing all the blocks???
I would try to reduce the features loaded from external sources as much as possible.
