Hello,

Our demos might appear slow, but this is only because we are showcasing lots of images with the highest quality. As such these images are not optimized and are making the load times higher.
Also, our demo pages try to showcase all options at once, so you can see all the possibilities the theme could offer.

Here are some general tips for speeding up your website:

a. Consider optimizing your images with some tool like this one:
www.jpegmini.com

b.  Also you can install some plugin for cache, like WP Fastest Cache or some other:
https://wordpress.org/plugins/wp-fastest-cache/
https://wordpress.org/plugins/wp-super-cache/
https://wordpress.org/plugins/w3-total-cache/
c. Enable gzip compression on your server. You can read more about it here:
http://www.feedthebot.com/pagespeed/enable-compression.html

But it comes down to pasting this code to .htaccess file located in your folder:

<ifModule mod_gzip.c>mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file .(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
</ifModule>

d. Also check - Leverage browser caching:

e. Use at least PHP 7 or greater in order to process PHP code faster.

Kind Regards,
