Yes, this is potentially a serious issue, especially if you rely on the canonical to point multiple versions of a page to a single page for indexing purposes. The canonical URL should have a full protocol, domain, and path. If you're using Wordpress, take a look at the Yoast plugin, for injecting canonical links.

If you have in the morning 3.8 seconds and in the evening 2 seconds, it could mean that either the tool to test your website is "busy" or the server your website is on is "busy". A server thats on a higher load takes a bit more time to complete loading the website.

Hi there, DA and MozTrust metrics are correlated, but not affecting each other. Actually, I believe MozTrust is not really being even used anymore. DA kinda took over. Basically, you should care about DA and SpamScore. Here are a couple links to other answers, explaining what it is, the differences etc: https://moz.com/community/q/mozrank-and-moztrust https://moz.com/community/q/how-do-i-increase-my-trust-score Hope this helps.
