how to test load balancing

With the development of information construction in various industries, people put forward higher requirements for the processing ability and high availability of the network server. Especially in highly information-based enterprises, the key network services have become an important part of enterprise generation process, interruption of service means the interruption of production and the loss of opportunity. Load

accordingly. 2048 should be satisfied for most people, but to be honest, if your traffic increases, it should be clear about the number of workers.CPU priority Setting the CPU priority basically means that you tell each program to use the CPU core, and they will only use this CPU core. I don't want to say a lot about this one, but you need to know that if you are going to do this, you mustVeryBe careful. You must know that the CPU scheduler of your operating system can process

One of Linux load Balancing software LVS (concept article) A brief introduction of LVSLVS is the short name of Linux virtual server, the Linux VM, a free software project initiated by Dr. Zhangwensong, and its official site is www.linuxvirtualserver.org. Now that LVS is already part of the Linux standard kernel, Before the Linux2.4 kernel, the use of LVS must be recompiled to support the LVS function module

Server cluster with a balanced policy　　Nowadays, servers must be able to provide a large number of concurrent access services, and their processing and I/O capabilities have become bottlenecks in service provision. If the customer's increase causes the communication volume to exceed the capacity of the server, the result will inevitably be: downtime. Obviously, the limited performance of a single server cannot solve this problem. The processing capacity of a common server can only reach tens of

CEF (Cisco Express Exchange) detailedCEF Load BalancingOne, the destination-based balance of responsibility:Destination-based load balancing allows routers to use multiple paths to balance the load. For a source/target host, packet forwarding takes the same path, which is handled even if multiple paths are available. D

A mention of load balancing, I believe many students will directly think of nginx reverse proxy, because we are usually more familiar with Nginx to do Web services load balancing. In fact, Nginx is only part of the load balancer, and each level in the Web application actuall

configure the IP address of the RAC and use the DHCP service to assign IPOracle official recommended Gns+scan method, you can hide the cluster nodes of the IP, the client only through a specific name to access the cluster, do not need to ignore the cluster node increase or decrease or IP changes, but still need to rely on DNS and DHCP services, the client also needs to set a specific DNS address, Multiple points of failure in the actual production environment is not useful.Thus there is a most
