Ipvs load Balancing in the kernel is scheduled to be a connection-granularity. In the HTTP protocol (non-persistent), each object obtained from the Web server needs to establish a TCP connection, the same user's different requests will be dispatched to different servers, so this fine-grained scheduling to a certain extent, can avoid the burst of individual user access caused the load imbalance between servers.On the connection

Scheduling Algorithm
The operating system manages the limited resources of the system. When multiple processes (or requests from multiple processes) need to use these resources, because of the limited resources, the process (request) must be selected to occupy resources according to certain principles. This is
Today, let's take a look at the process scheduling of linuxcpu. for linux servers, we usually encounter two problems: 1. real-time performance, is there any way to ensure that a process runs preferentially and is not restricted by the time slice? other processes can run only when it is finished? 2. Multiple

The following algorithms are available in QoS queue scheduling:
1. SP
SP: strict priority (strict priority). SP scheduling sends the group in the higher-priority queue in strict order of priority from high to low. When the higher-priority queue is empty, resend the group in the lower-priority queue. The queue 7 has the highest priority and the queue 0 has the lowest priority.

The scheduler is responsible for deciding which process to run, when to run, and for how long, and the process scheduler can be seen as a kernel subsystem that allocates a limited amount of processor time resources between the running state processes. Only through the rational sc

[Abstract] Linux is a multi-user and multi-task operating system. It implements fair and efficient scheduling for multiple processes, rather than using a single scheduling policy, instead, several scheduling policies are organically integrated.

These tasks, although they are in memory, are not in a functioning state. These processes use the kernel to block themselves until an event occurs.Multi-tasking systems can be divided into two categ

Linux Process scheduling principle
The goal of Linux process scheduling
1. Efficiency: High efficiency means more tasks to be done at the same time. The scheduler is executed frequently, so the scheduler should be as efficient as possible;
2. Enhance interactive performance: In the system under the load, but also to ensure that the system response time;
