How to limit disk usage by the Java web plugin?

While it is true that fewer and fewer web applications require Java, they are still widely used. And if there is something that characterizes Java is the solidity and stability but also the consumption of resources. In this sense, the same web browsers are consuming more and more resources thanks to the extensions and their design. So, if you are running a Java application on the web and it is heavy the java plugin will consume more and more disk and can cause a problem. That’s why, in this post, I will show you limit disk usage by the Java web plugin in the web browser.

The Java control panel

The Java Control Panel is a small application built into Java that allows you to control the behavior of the Java web plugin. It has several tabs with different options according to our needs.

An example of the utility of this utility is that with it, we can use a proxy only for the Java web plugin. This way, we won’t affect our main connection. On the other hand, we can also define which JRE to use if we have several installed.

Besides all this, this utility allows you to update the plugin frequently. And of course, it allows limiting the use of the disk by the plugin.

The Java Control Panel comes when Java is installed on the computer. However, it does not have a launcher in the main menu itself. So maybe it’s a bit hard to locate it.

To launch it, open a terminal emulator and run this command:

:~$ jcontrol
