Lately, it’s all about optimizing your website and making it as fast as possible. Especially since search engines like Google consider page load time as a ranking factor. And, of course, the load time is a huge factor in user experience.
Aside from using a fast, SSD-powered VPS, you can also do some other tweaks and settings to speed up your website, like enabling gzip compression in Nginx.
Here we’ll discuss one method that will increase the transfer speed by reducing the size of the files with compression. This method will also bring up the benefit of reducing the bandwidth that is used in this process and will make the hosting cheaper to the owner (ie, you can use a hosting plan with fewer resources. The best part about – it’s easy to do and it will only take you a few minutes.

With Monit, you can check a certain filesystem. As we are using include /etc/monit.d/* (it’s just another way of configuring Monit, you can put all of this in /etc/monit.conf too), we need to first create the appropriate file for the check we are about to configure. You can also name the file to your liking, it does not have to be the same as the example.

Being a Linux system and network administrator requires a lot of time and dedication. Sysadmins usually have hundreds of tasks they need to do every day, some of which may be repetitive. This is where the sysadmin tools come in handy. There’s an open source application for just about anything. You can get a lot more work done if you’d automate repetitive tasks and manage your time properly. If you are in tech support, you’ll most likely use and support hundreds if not thousands of different software and applications. Managing all of them at the same time, or with even just a small number of them can be difficult if you don’t use the proper tools.
