As my computer aged, it got slower, especially about doing something different from what I had been doing. Since going slow is often an antidote to today's anxious frenzies about immediate results, the machine's nature alerted me to all sorts of mini-speeds in my life. From the time it takes to switch channels, or get an email I just sent myself, I became more aware of transmission speeds and loading/reloading speeds.
In today's world of computing and interneting, a whole lot of transmission goes on. If the web page doesn't reload, you can click on the "re-load" symbol to have the file that creates the page re-sent, often in an updated form, unless the reload is requested too quickly and the new version didn't register yet.
Transmission and reloading takes place inside us, too. In fact, our senses often refresh quickly and automatically but as we age, the processes may slow down. I learned from Robert Ornstein about the priorities our bodies usually use for sending messages and updates to our conscious mind.

As with computer files, we are often concerned with what happened recently, sometimes very recently, like in the last 10 seconds. If something is exciting, especially vivid or meaningful, it gets our attention, too. If traffic on the roads or on the internet is very heavy with lots of users, speeds can be reduced. When I ask Netflix to show me a movie, it may take a moment to load the show, maybe several moments if many others are doing the same. Some people have t-shirts about loading speed:
