Yes, Google always scores with 20-40 points mobile performance for 99% of websites built with WordPress. To get more points you need to have a really light page. For example remove all sliders, carousels and leave a few banners and products only. Then you will get a high result. But usually, our theme works very fast on mobile devices and don’t have any problems with performance. We suggest you to test it on a few mobile devices and you will see that there are no real performance problems.
We usually test with Google and GTmetrix tools. You can read suggestions and tips regarding the problem discovered by them on your website and try to improve the situation.
CSS files and jquery library have to be loaded at the beginning before all resources to prevent appearance issues while styles are not loaded. But the loading time for these resources should be smaller but it doesn’t depend on the theme. Contact your hosting provider or use some kind of CDN that should increase that speed.
We see also some 404 errors for some resources. Check your sliders thumbnails in Revolution slider, they lead to 404.
