In multi-core CPUs, it is important to ensure that the tasks assigned to each CPU have a good load balance in order to perform the performance of multiple CPUs well. Otherwise, some CPUs are running, others are idle, and they are not able to perform the benefits of multicore CPUs. To achieve a good load balance there are usually two scenarios, one is static load

protocols, such as the Outlook Web App. So on the load balancer this layer, no longer special need for the load office weighing products to support client affinity.Let me say a few more words, from the level of the mailbox connection to the level of the Web connection request. As mentioned earlier, older versions of Exchange have problems requiring clients to re-authenticate without client affinity support
following point in time:1, non-running normal processes become real-time processes (such as through the Sched_setscheduler system call);2, after the dispatch (there may be a real-time process is preempted by higher priority real-time processes);3, the real-time process is awakened, if not immediately run on the current CPU (it is not the current CPU on the highest priority process);It seems that the load balancin
In multi-core CPUs, to make full use of the performance of multiple CPUs, you must ensure a good load balance for the tasks allocated to each CPU. Otherwise, some CPUs are running and others are idle, so they cannot take advantage of multi-core CPUs.There are usually two solutions to achieve a good load balancing: static load

What is load balancing?When the performance of a single server reaches its limit, we can use a server cluster to improve the overall performance of the site. Then, in the server cluster, you need a server to act as the dispatcher's role, all of the user's requests will be first received by it, the dispatcher then according to the load situation of each server to
mainly implements the following tasks: solving network congestion problems, providing nearby services to achieve geographic location independence, providing users with better access quality, and improving server response speed; this improves the utilization efficiency of servers and other resources, and avoids spof in key parts of the network. In fact, Server Load balancer is not a traditional "Server Load
