free load balancer linux

Turn from http://blog.csdn.net/szchtx/article/details/38455385 thanksLoad is an important indicator of the Linux machine, which intuitively reflects the current state of the machine. If the machine load is too high, then the operation of the machine will be difficult.Linux has a high load, mainly due to CPU use, memory usage, IO Consumption is composed of three p

processing is not important, in fact, two quad-core processor equals four dual-core processor equals eight single processor. So, it should have eight processor cores. Let's take a look at the output of uptime: This is a 4-core processor, and the results also show a lot of free resources. The reality is that even if it peaked at 2.8, I never thought about its load problem. So, how can there be three numbers

of the top command is detailed The top command is a commonly used performance analysis tool under Linux to display the resource consumption status of each process in real time, similar to the Task Manager of Windows. The following is a detailed description of how it is used. Top-02:53:32 up, 6:34, users, load average:0.24, 0.21, 0.24 tasks:481 Total, 3 running, 474 sleeping, 0 stopped, 4 zombie Cpu (s)

The background is this:The implementation of a module in C + + in a project requires a multi-threaded approachWhere the hot load needs to be implemented, this part when the configuration file changesWill cancel the unwanted thread if needed, and create a new thread if neededHowever, after observation, it will be found that each time the configuration file is updated, the resources requested by the deleted thread have not been released.The Virt field o

In peacetime operations, when a server has a performance problem, it usually looks at the current CPU usage, especially the load of the CPU (load average).To get the CPU load of the server, there are three kinds of commands:1) w command [[email protected] ~]# W 12:12:41 up 167 days, 20:46, 2 users, load average:0.00,

The latest 10 open-source stress/load testing tools in linux The load/stress testing tool can help you understand the execution of applications under load/pressure. It can expose problems and improve the performance. Therefore, load/stress testing is essential to ensure syst

Linux system if you want to understand the load between multiple database servers, then you will use the Clustershell tools, as a Linux operation tool, its installation and configuration is also a learning, then on Linux to install and configure Clustershell? 　Installation and configuration of Clustershell

Recently a Linux server abnormal, the system reflects very slowly, the corresponding application can not be reflected, but also in the case of freezing, after several days of observation, found that the server pressure is very large, the main pressure from the hard drive IO access has reached 100%In order to make it easier for you and yourself to meet this problem as soon as possible, I will look at the Linux
