@sgunhouse said in need information about website loading.:

We are not a search engine, nor are we here for your advertising or SEO.. Honestly though, your site is slow - I checked before deleting the link.

As said by @sgunhouse
Opera is not a search engine; it is a browser. The speed of your website does not depend on the browser as it is an update browser.
Older versions of browsers may be unable to load specific assets and code because they're not compatible.
But Opera is an updated browse, so it will not affect your speed.
