Hello brother Lukecav. You have helped me to get this issue nearly solved and those who had questions like me they will get the help for the lifetime from this post and comments.
Brother one last question. What about those domains which have www. before the domains?
Example:
www.google.com
www.googletagmanager.com
www.google-analytics.com
Should we be adding these domains like this:
//www.google.com
//www.googletagmanager.com
//www.google-analytics.com
or like this:
//google.com
//googletagmanager.com
//google-analytics.com
Thank you in advance.
With www is fine on those sites.
Only use the external site URLs that are being requested on your site and no it will not slow your site down, the idea is that the DNS requests that are external will be prefetched for the site user.

lukecav - I hope that you or someone else in this forum may be able to clarify this for me. I added //soundcloud.com to my dns prefetch list. I am still having issues (see attached file) Should all these be added too: //wave.sndcdn.com, //w.soundcloud.com
I also came across code.ionicframework.com when running a test - should this be added to my prefetch list as well?
Any feedback would be greatly appreciated!
assume list
Thanks Luke for DNS prefetching list. I have applied on my website but still performance is not good. What others things to consider for the best speed performance.
The site performance seems decent. https://gtmetrix.com/reports/www.aroundrobin.com/6r7d1ab9/

You will need to add
