Some previous considerations.

Both elements are configured to be used as needed. Moreover, this happens on a PC, tablet, mobile, or any other device. This behavior is also intended to increase the durability of the components. For example, it is illogical to activate all the cores of a processor to surf the Internet. Now, this in a desktop computer does not represent a major inconvenience. Apart from energy consumption. However, on a laptop, it is a different story. Since it depends on a battery, it is fundamental to the energetic balance. Therefore, it is only necessary to use all the power in specific cases.

On the other hand, before continuing, it is necessary to know the computer specifications. With this in mind follow the following path: Windows Settings>System>About.

This allows knowing the total RAM memory installed in the computer. In addition to the type and architecture of the processor.

Using all RAM and all processor cores in Windows 10.

Now it is necessary to enter the system configuration. With this intention, you can search in the search box. Or simply run the appropriate command. To do this, press the Win+R combination. Then run msconfig.

Consequently, you will be redirected to the system configuration. Please click on the Startup tab. Once there, click on the Advanced Options button.

Now we will access the RAM and processor configuration. Please note that you must multiply the total RAM by 1024. This is in order to get the maximum value we can use. Therefore, you must add this value to the assigned box. On the other hand, if you don’t do it, the system will use the RAM it considers necessary.

Now it is time for the processor. Consequently, uncheck the Number of processors box. On the other hand, for the specific core usage, check the box and select the value.

Just save the changes. Ultimately, we have seen how to use all the RAM and the processor in Windows 10, which allows you to take full advantage of your computer’s potential. Or on the contrary, limit the use. See you later!

1- Install EPEL Release if CentOS or RHEL

dnf install -y epel-release

2- Install Linux Monitoring Sensors

Install lm sensor on RHEL 8 and CentOS 8 and Fedora

dnf install -y lm_sensors

Install lm sensor on RHEL 7 and CentOS 7

yum install -y lm_sensors

If you are using Debian or Ubuntu use following command

sudo apt-get install lm-sensors

3- Sensor Configuration

Now, we need to make some configuration using below command after lm sensor installation. So if you want to go with default configuration simply hit enter key step by step.

sensors-detect

You will see similar steps during configuration.

[root@osradar ~]# sensors-detect

 Some Super I/O chips contain embedded sensors. We have to write to
 standard I/O ports to probe them. This is usually safe.
 Do you want to scan for Super I/O sensors? (YES/no):
 Probing for Super-I/O at 0x2e/0x2f
 Trying family National Semiconductor/ITE'...               Yes Found unknown chip with ID 0x1911 Probing for Super-I/O at 0x4e/0x4f Trying familyNational Semiconductor/ITE'…               No
 Trying family `SMSC'…                                     Yes

 Some systems (mainly servers) implement IPMI, a set of common interfaces
 through which system health data may be retrieved, amongst other things.
 We first try to get the information from SMBIOS. If we don't find it
 there, we have to read from arbitrary I/O ports to probe for such
 interfaces. This is normally safe. Do you want to scan for IPMI
 interfaces? (YES/no):
 Probing for IPMI BMC KCS' at 0xca0...                      No Probing forIPMI BMC SMIC' at 0xca8…                     No
 Some hardware monitoring chips are accessible through the ISA I/O ports.
 We have to write to arbitrary I/O ports to probe them. This is usually
 safe though. Yes, you do have ISA I/O ports even if you do not have any
 ISA slots! Do you want to scan the ISA I/O ports? (YES/no):
 Probing for National Semiconductor LM78' at 0x290...       No Probing forNational Semiconductor LM79' at 0x290…       No

 Lastly, we can probe the I2C/SMBus adapters for connected hardware
 monitoring devices. This is the most risky part, and while it works
 reasonably well on most systems, it has been reported to cause trouble
 on some systems.

 Do you want to probe the I2C/SMBus adapters now? (YES/no):
 Sorry, no supported PCI bus adapters found.
 Module i2c-dev loaded successfully.
 Next adapter: i915 gmbus ssc (i2c-0)
 Do you want to scan it? (yes/NO/selectively):
 Next adapter: i915 gmbus vga (i2c-1)
 Do you want to scan it? (yes/NO/selectively):
 Next adapter: i915 gmbus panel (i2c-2)
 Do you want to scan it? (yes/NO/selectively):

So, you will see similar screen upon successful configuration.

4- See CPU Temperature

Finally issue following command to see CPU temperature,

sensors

So, you can see in above image the command “sensors” is showing number of CPU cores its current temperature. But in brackets its is also showing high and critical temperatures in degree centigrade.

See temperature on Runtime

watch sensors

Check temperature in Fahrenheit

Then, what if you wanna see it in Fahrenheit, if you want to do so simply run below command.

sensors -f

That’s it.

Uninstall unused applications

On many occasions, there are a lot of applications in the system that we never or hardly ever use. Worst of all, they take up space on the hard drive and often run in the background, consuming CPU and RAM resources. With this in mind, we need to type control on the search bar, to enter in Control Panel. Now we just have to choose the application we want to remove, double click on it and the uninstallation process will begin.

Uninstall pre-installed programs

Windows 10 comes with some pre-installed applications, some of them useful, others not so much. In the same way, Windows 10 comes with some pre-glazed applications, some of them useful, others not so much. For these cases, we have to type in the search bar: app and select Add or remove programs.

A list with the applications will be displayed, we only have to click on the one we want to uninstall.

Disabling startup apps

There are situations where we cannot uninstall an application because it is useful for us. But it is the case that it starts when the system boots, and remains in the background consuming resources. For this purpose, Windows includes a tool that allows you to view applications that start at startup. To activate it, just type startup in the search bar and enter in Startup Apps.

The following box contains all applications configured to start when we log in. In addition, we can see the impact they cause in the system and the option to disable them.

Disable Visual Effects

Windows 10 comes with visual effects on windows, tabs, and menus. These are activated by default in the system, and their impact on powerful machines is almost imperceptible. But when we work with more modest equipment, it can become a problem. For that reason, we can disable it by typing in the search bar appear in order to click on Adjust the appearance and performance of Windows.

in the next window select the tab Visual effects, and choose Adjust for best performance. This will disable all visual effects, you can also choose the Custom option to select which effect you want to deactivate.

Defragment the hard drive

Another option to improve the performance of the system is to defragment the hard disk. To do this, type defragment in the search bar Another option to improve the performance of the system is to defragment the hard disk. To do this, we write defragment in the search bar until it appears to defragment and optimize drive. In the following box, select analyze and then optimize, to improve the performance of the hard drive

Delete temporary files, free up disk space, and clean up the desktop

As we use the system, surfing the Internet, installing programs, the disk is filled with unnecessary temporary files. Windows 10 has its own tool that allows you to erase temporary files, and free up space on your hard drive. This tool is called Disk Cleanup, and to activate it just type Disk Cleanup in the search bar. We select the disk to clean and the items that we want to eliminate. This is also the option to clean up system files.

Keep the drivers updated and Windows 10 itself

it is imperative to have always correctly updated the drivers of our PC, as well as the installed applications and the own operating system is going to help us to improve the performance of Windows 10 and to accelerate the system. Any problem, incompatibility or obsolete driver can make certain components not work properly and the performance of our equipment is not optimal.

OK, that’s all for now, with these simple tips we can improve the performance of our team with windows 10. If you want to know more about our favorite system, I invite you to review our tutorial about installing Docker on Windows 10.

With this, you know how to increase the CPU performance on Windows 10.

The post Increasing CPU performance in Windows 10 appeared first on Linux Windows and android Tutorials.

The vulnerability affects all the Intel CPUs of the Core-based series, according to Intel’s official statement. The horrible thing is, it’s present physically inside the processors, meaning that any operating running on any Intel Core-based CPU will be vulnerable to the attack.

What is Lazy FPU context switching?

At first, let’s talk about the vulnerable section of the CPU. Lazy FPU context switching is a performance optimization feature. It’s responsible for saving and restoring the FPU (Floating Point Unit) registers. These registers hold the floating point numbers and allows access to those whenever necessary.

Now, the bug here is physical. The physical bug in the CPU allows other processes to sneak into these registers along with their data.

The problem is, these numbers are necessary for various important tasks like cryptographic equations. Thus, a hacker may be able to sniff out numbers from these registers to crack an encryption key. The next moment, everything else will be gone.

The scope of the vulnerability

Despite it’s a major CPU bug in the processors, it’s not executable using a web browser. That makes this vulnerability less effective than the Meltdown. Meltdown is preventable with operating system patches in cost of performance.

Rumors about the bug

Before the vulnerability was officially disclosed, there were rumors about it since DragonflyBSD and OpenBSD released notices about patches that would fix this vulnerability. The notice was a strong indication that there was something wrong with the FPU registers in Intel’s processors.

Thankfully, this bug is preventable without changing the existing microcode. That’s a big relief for Intel whereas vendors are working for fixing the issue with future patches.

Here is a list of all the official statements of different vendors.
