1.CPU frequency higher performance? not necessarily. This is in many novice among the misunderstanding. CPU performance depends on a number of comprehensive parameters, not necessarily the root frequency proportional. Of course, in the same series of CPUs, such as Celeron 4, the higher the frequency of high performance. 2. Why Celeron High-frequency Low-energy? And the Fast Dragon series Low-frequency h

This blog post focuses on the features and functions of the CPU registers around the base part of the registers in the 80x86 CPU.ObjectiveFirst, let's introduce the history of Intel CPUs.Intel CPU Series, initially 4-bit microprocessor 4004, then to 8-bit microprocessor 8008, then 8-bit microprocessor 8080, and later 16-bit microprocessor 8086.Starting from 8086, Intel entered the so-called x86 era.Intel 80

CPU usage depends primarily on what kind of resources are running on the CPU, such as copying a file that typically consumes less CPU, because most of the work is done by DMA (Direct Memory Access), but after the copy is complete, the CPU knows that the copy has been completed. Scientific computing usually takes up mor

Now people buy mobile phones, are more concerned about the use of what CPU, because the CPU directly determines the performance of the phone, the CPU on the phone is like a human brain, it is the entire mobile phone control system, is also the logical part of the control center. Also equivalent to the engine of the car, the more powerful the engine, the faster th

I like Oracle very much. I also like to sum up the experience and lessons on optimizing the CPU usage of Oracle in my work. Let's talk about this question in detail. CPU is one of the servers I like Oracle very much. I also like to sum up the experience and lessons on optimizing the CPU usage of Oracle in my work. Let's talk about this question in detail.

Nowadays, there is no uniformity in the naming of the same thing on the Internet. It seems like there are many types of things, so it is necessary to clarify the clues first, find out the equivalence relationships between different names: 1. CPU external frequency = External frequency 2. CPU frequency = clock speed 3. Frontend bus frequency 4. System bus frequency 5. MultiplierRelationships: The externa

In fact, the people who write Java seems to have nothing to do with the CPU, at most and we mentioned in the previous how to run the CPU full, how to set the number of threads is a bit of a relationship, but the algorithm is only a reference, many scenarios need to take practical means to solve can And we'll consider how to make the CPU not so full after the

Without nagios monitoring software, as long as the server can access the Internet, you can send an email to remind the administrator of the system load and CPU usage. 1.

The best synchronization technology is to put the design of critical resources that do not need to be synchronized first. This is a way of thinking, because each explicit synchronization primitive has a performance overhead that cannot be ignored. The simplest and most important synchronization technology includes declaring kernel variables or data structures as per-CPU variables ). Each CPU variable is mai

CPU and memory are the most reasonable (both the CPU and memory have the corresponding speed and bandwidth. In the computer configuration process, the CPU speed and bandwidth are used together with the corresponding rate and bandwidth memory, which will directly affect the performance of the entire machine. Improper combination will often waste

For the majority of computer users, CPU cooling is a top priority, whether it is the CPU produced by Intel or AMD, cooling the CPU is very important. Mainstream processors consume a lot of power and generate high heat. In this way, the CPU cooling requirements are more stringent. With the launch of the more powerful Pe

Understanding cpu system load in Linux 1. View System Load If your computer is slow, you may want to check whether it is too heavy. In Linux, we generally use the uptime command to view (w command and top command ). (They also apply to Apple's Mac computers .) If you type uptime in the terminal window, the system will return a line of information. The second half of this line shows "load average", which means "average system load". There are three nu

Two years ago, Microsoft's Asian Research Institute published the book "The beauty of programming". Chapter 1 section Section 1 "let you know the CPU usage curve, it can be said that it has set off a game-to-CPU usage curve nationwide. I am even thinking about how to handle the CPU usage curve while taking the bus. The book provides such a refreshing figure, attr

In the previous article, we mentioned the general classification of virtualization technology, which is divided into 3 categories: full virtualization, semi-virtualized, and hardware-assisted virtualization technology. And the main virtual body of our virtualization technology is our hardware CPU, memory and IO, so how does our CPU work in full virtualization mode? How does the semi-virtualized work? How do

CPU affinity refers to the ability to bind one or more processes to one or more processors on a Linux system. The CPU affinity mask for a process determines which CPU or CPUs the process will run on. In a multiprocessor system, a mask that sets the affinity of the CPU may achieve better performance.A

How to learn more about CPU information in Linux systems. Of course, it is checked by Cat/proc/cpuinfo, but for example several physical cpu/several cores/several threads, these questions how to determine. After viewing, my development machine was 1 physical cpu,4 cores 8 threads, Intel (R) core (TM) i7 CPU 860 @ 2.80G

a basic unit of CPU scheduling, and a process is a basic unit of system resource allocation, and a process may contain multiple threads. Multithreaded programming has four advantages, such as high responsiveness, resource sharing, economic and multi-processor architectures. While we can have many threads in our user process to execute, these user threads are actually mapped to kernel threads to execute. The mapping relationship model between the use
