Generally I'd expect a primer to have a bit more information than this. I understand that it's a sales page for your software and services, so calling it something other than a primer would probably be fitting.

You're right, and there's of course a lot more to discuss. I'm just angling for ideas about what directions people are interested in and whether the topic raises any interest at all.

How did this get upvoted so much for something that has so little substance?

    In general, the causes for slowness can be divided into two categories:
    1. A slow server.
    2. A heavy page.

A slow connection, a slow computer, a computer busy running other processes, a slow browser, a browser with hundreds of open tabs... the list goes on and on.

Thanks for your comment, I'll cover this angle.

Of course, none of those factors can be influenced by the site itself, and all of those factors influence all sites at the same time. We're focusing on things we can improve.

Although it's a simplification, I believe it's broadly correct to categorize things this way. The main reason to highlight this is because oftentimes people (clients) will focus too much on the "heavy page" part, because that is what measurement tools like Google PageSpeed Insights mostly tell you to improve.

TS;DR: Speed up server, reduce weight of page and external dependencies, test speed from different locations.
