Irqbalance of CPU optimization of Linux system

First: Service Introduction

This service is dedicated to interrupt service instructions!

can guarantee the reasonable distribution of multi-core CPU at the system level!

Second: Installation method

# # Yum-y Install Irqbalance

#/etc/init.d/irqbalance Start

Third: Advantages and disadvantages Analysis:

Advantages: It can improve performance and reduce energy consumption.

Principle: Irqbalance optimizes interrupt allocation, which automatically collects system data to analyze usage patterns and puts the working state in performance mode or Power-save mode depending on the system load condition.

If you feel a detour, it is more than one horse, and the coachman is irqbalance!.

Disadvantages:

Because Irqbalance chooses its own algorithm, multithreading service, there will be potential allocation failure problems, resulting in performance instability!

IV: Selection criteria:

Mainly by the system to carry the hardware and the load of software to decide!

Example:

A general-configuration file server can open irqbalance service completely;

A well-configured Oracle database server does not need to turn on this service at all (Oracle itself has a scheduler, irqbalance itself consumes resources, ultimately, must pay attention to the shortcomings of the third step)
