The more content you add to your website over time, the slower it will run. There are often a few causes for this common problem, but there’s a good chance that your site is slow because you’ve finally hit your shared hosting limits. In order to boost your site’s speed, it’s a good idea to upgrade from shared hosting to VPS hosting to decrease page loading times.
A regular user account with superuser privileges, on the other hand, needs to add the sudo prefix to any command it wishes to run using administrative privileges. This may seem like a small change, but it makes a huge difference. With this approach, you’ll need to think twice before running any command using the sudo prefix, which can help you avoid mishaps.
Essentially, here’s the criteria I would use to judge things – if your site is made up of primarily static, HTML-based content, then you probably don’t need a VPS package.  However, if you have a large amount of files stored, multiple sites, dynamic content, and the possibility of major traffic from time to time, then you might consider upgrading to a VPS. It’s a powerful package that allows you to do more than you could with a shared hosting plan, but requires less investment than a dedicated server.

The most obvious and popular reason for a VPS is to run a single website, or multiple websites. However, you can use them for pretty much anything that requires access to the internet – such as a web application like Nextcloud to run your own Dropbox alternative – or to create your own virtual private network to better secure the internet connection of your PCs and mobile devices.
