Joomart Megastore template, latest Virtuemart and Joomla
In general, the site turned out to be stable, functional and with a good design. But I checked the loading speed of the site's main page and it is 7+ seconds. This is not bad, but for search engine optimization it is better to keep the site speed in the range of 3-5 seconds.

Sorry, this is T3 template from Joomlart.
Now is used JS and CSS optimalization inside template and now is not more what can owner do it for optimalization - only add support for webp and optimalization sizes of images.
With only click and setup from admin - this is end of optimalization.
Using cache or other plugins for optimalization is wrong way.
If you need load website quickly - 1-3 sec, then must comming develloper and change T3 and eshop completelly. (cca 50-150 hours, for develop, testing and more).
Look at the www.zelenazeme.cz and look test in pagespeed insight from google.
