Opera GX: the browser for players and their GX controls under Linux

There are a multitude of web browsers for GNU / Linux, like Opera. It is precisely this developer who is today the protagonist of this article. And, although there are lighter, more efficient, more secure, more secure, respectful of your privacy / anonymity, etc., The truth is that there are not many like Opera GX. He’s a browser for players.

Opera GX came out alone For Microsoft Windows for the moment, But many players who use Linux hoped that this would finally happen for our favorite operating system and would not happen like other similar opera projects that have not finally arrived. But the truth is that almost a year has passed since the launch and still nothing.

This free Opera GX software has very interesting features, such as The GX Control. It is a series of utilities or navigation tools with which you do not need to close the program to obtain more performance of the machine directed to other software. Instead, with GX Control, you can choose the amount of RAM, the quantity of CPU time and the quantity of network that the web browser will use as much as possible.

In this way, bandwidth, memory and CPU resources intended for video games would not be damaged. And you might think … Why do you tell me that if Opera GX may not come under Linux, or maybe you are already satisfied with your web browser. Well, very simple, and in GNU / Linux you don’t need GX Control, the power of penguin is enough.

In other words, you can use certain options that GNU / Linux gives you Have your own GX Control without the help of Opera:

• 1 Limit the bandwidth consumed by a process:
• 2 Limit RAM resources used by a process:
• 3 Limit CPU resources used by a process:

Limit the bandwidth consumed by a process:

To limit the bandwidth or the use of the network that a process or a program made on your Linux, there are also several options. One of them is to use the maintenance program, another is Wondershaper. You must install the two packages, because they are not pre-installed in default distributions. Regarding use, you can choose one or the other, as you prefer, even if what Wondershaper does is to limit the traffic of all programs at the same time by interface interface . Here is an example of how the net would be used to limit network consumption from, for example, Firefox:

Trickle -d 40 -u 10 Firefox

With this command, you limit the use of the network for Firefox to 40 ko / s and 10 ko / s of Download and download respectively.

Limit RAM resources used by a process:

For limit the amount of RAM that a process can use Anyone under Linux, whether it is a web browser or whatever you want, you can use the program name itself that you want to limit. For example, imagine that you use the Firefox web browser and want to limit the RAM to only 0.5 GB, or 500 MB. To do this, you can use Systemd in this simple way:

Systemd -Run - -Scope -P Memorylimit = 500m Firefox

You could even use control groups to modify processes groups in one go . And of course, Ulimit as I have already explained in other LXA articles.

Limit the CPU resources used by a process:

If what you want is limit the use of the processor that a program makes, So that will interest you. For this, there are several options, from the use of certain tools that Systemd offers you, to the famous renice, cpulimit, stress, etc. For example, use PS to locate the process (and its PID, for example, suppose that it is in 8188) corresponding to the program you want to modify. Once you know, you can use Renice to modify its use of the processor. Remember that the accepted values ​​range from -20 to 19, the highest positive points being those who consume the least. If you wanted to give him the least favorable value so that he hardly consumes:

RENICE +19 -P 8188

Alternately Install CPULIMIT, Since this package is not included in your distribution. Once you have installed it, you can limit your processoring quota to, for example, 25% of one of the following two ways:

CPULIMIT -L 25 -P 8188 & CPULIMIT -L 25 FIREFOX &

You can even go further and also make other types of limits or management, such as those of E / S as I explained here.
