You see the CPU metrics:But what does all of those 2-letter abbreviations mean?The 3 CPU statesLet's take a step back. There is 3 general states your CPU can is in: Idle, which means it had nothing to do. Running A use

Recently responsible for the SVR pressure is large, business logic is a little more complex, can optimize the place has been all optimized, Currently 3k per second, CPU load is still relatively high Top look, 4 core CPU load is not too balanced, it is intended to consider the business process is assigned to 3 CPU running, the other

In Linux, you can view CPU and memory usage during system maintenance. you may need to view CPU usage at any time and analyze the system status based on the relevant information. In CentOS, you can use the top command to view CPU usage. After running the top command, CPU usage... in Linux, you can view

For modern CPUs, the performance bottleneck is access to memory. CPU speeds are often at least two orders of magnitude higher than main memory. So the CPU has introduced L1_cache and L2_cache, and the higher-end CPUs have joined the L3_cache. Obviously, this technique raises the next question:If the memory that a CPU needs to access at the time of execution is no

In the Linux operating system, we generally look at the CPU load of the system commonly used commands can be uptime,top, as well as vmstat and so on are all possible. The information provided by each tool is different,I'm going to talk about the CPU section here. Using the uptime command, you can get the operating system in the last 1 minutes, 5 minutes and 15 minutes of the

what is the normal temperature of the CPU? The normal temperature of the CPU AMD processors: AMD Althon, Althon Opteron, Duron and Sempron series AMD Athlon XP 1.33ghz+ 90 degrees AMD Athlon XP t-bred upto 2100+ 90 degrees AMD Athlon XP t-bred over 2100+ 85 degrees AMD Athlon XP Barton 85 degrees AMD Athlon 64 70 degrees AMD Athlon (Socket 939, 1.4 volts) 65 degrees AMD Athlon 70-degree FX AMD At

CPU's frequency, that is, CPU core working clock rate (CPU Clock Speed). It is commonly said that a certain CPU is how many MHz, and this number of MHz is "CPU frequency." Many people think that CPU is the speed of its operation, but it is not. The CPU's frequency indicates

Most users believe that the high-speed download of the Thunderbolt will occupy too high a CPU occupancy rate, which is completely committed to the empirical error. In fact, the thunderbolt can be achieved high-speed, efficient and exist, the overall reduction of CPU occupancy rate. First, traces of the Thunder Why can reduce CPU occupancy rate 1. Deep understan

1.0 OverviewIn the Linux/proc file system, you can see the time slices that start at startup, all CPU consumption, and the time slices that the process consumes for a process. This is a cumulative value that can be "non-blocking" output. The process CPU utilization during this time can be calculated by obtaining two statistics of a certain time interval. So, is there a simple, non-blocking way to get

CPU load observation and performance monitoring in CentOS CPU load and Utilization CPU load and utilization are two different concepts, but they can all be viewed in the top command. CPU utilization shows the percentage of CPU occupied by the program in real time during runn

This article describes how to use cgroups to restrict cpu resources in Linux to avoid a process occupying all CPU resources. For more information, see This article describes how to use cgroups to manage cpu resources. Let's talk about the cpu usage of the control process. When running multiple programs on a machine tha

Since Intel's 90um technology was launched, its new CPU does not use the previous clock speed to mark the CPU, but uses a number to mark the CPU, which causes Intel's CPU to have a model problem, intel uses this product to fully cover the high-end and low-end markets, but it also raises the consumer's blind choice of

View CPU information in CentOSWe can use/proc/cpuinfo to view CPU information. This file contains the data section of each processor on the system. There are six entries in the/proc/cpuinfo description for multi-core and super-thread (HT) technical checks: processor, vendor id, physical id, siblings, core id and cpu cores.(1) processor: including the unique ident

In QEMU/KVM, QEMU provides a simulation of the CPU, showing a certain number of CPUs and CPU characteristics of the client, and in the case of KVM Open, the execution of CPU instruction in the client has the hardware processor's virtualization function to assist the execution, which is very effective.QEMU/KVM provides the client with a complete set of hardware sy

Multi-core CPU A central processor has two or more cores! Pretty Head, with two or more brains! However, the running speed is not double that of a single-core CPU, because a single-core CPU is 100% running, and a dual-core CPU is 60% multiplied by 2 running. It requires three cores, 50% multiplied by three cores, 40% m
