When I start PageSpeed Insights analysis developers.google.com/speed/pagespeed/in...state%2F&tab=desktop it gives following recommendations:
Compressing iota.estate/…dia/sourcecoast/js/jq-bootstrap-1.8.3.js could save 317.2KiB (77% reduction).
Minifying iota.estate/…dia/sourcecoast/js/jq-bootstrap-1.8.3.js could save 251.4KiB (61% reduction).
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 16 blocking script resources and 18 blocking CSS resources. This causes a delay in rendering your page.
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.
Remove render-blocking JavaScript:

iota.estate/media/system/js/core.js?v=1502705446
iota.estate/…om_jfbconnect/includes/jfbconnect.js?v=6
iota.estate/…dia/sourcecoast/js/jq-bootstrap-1.8.3.js
Optimize CSS Delivery of the following:

iota.estate/media/sourcecoast/css/sc_bootstrap.css
iota.estate/media/sourcecoast/css/common.css
Please advise if these issues are manageable and if yes, how to manage them

Kind regards

Most of those are items we can't (or won't) do in JFBConnect itself. Re-arranging scripts is impossible because we can't control the load and insertion order from Joomla and your template.

Compressing and minifying the files is the only thing that we can do in JFBConnect. We don't because the Javascript files are marked to be cached, which means they are only loaded into the user's browser on the first page they hit of your site. After that, they should be cached and not re-loaded. So, there is some extra overhead from the larger filesize on the first visit to your site, but it vanishes on the 2nd or later visit.

There are plenty of plugins out there that work well with JFBConnect that are meant to do most of the above steps automatically. We've used, and seen many sites use, JCH Optimize in the past. It can cause it's own issues as there's a lot of configuration options in there, but it's the best place I'd recommend to start with to improve your PageSpeed score if that's critical to you.

Thanks,
Alex
