A method and device for optimizing the performance of read and write operations

Abstract

The invention discloses a read and write operation performance optimization method and device. The method includes: receiving a read-write request sent by a processor located in the processor cluster, wherein the read-write request includes the identifier of the processor; based on the identifier of the processor, querying the configuration table to obtain the information that the processor is currently running The identification of the virtual machine, wherein the configuration table contains the mapping relationship between the identification of the processor and the identification of the virtual machine currently running on the processor; the identification of the virtual machine is sent to the slave device, according to the virtual machine currently running on the processor Optimize the performance of read and write operations based on the identity of the machine. The above solution can know the identity of the virtual machine that sends the read and write request, and optimize the read and write operations according to the identity of the virtual machine.

Description

technical field [0001] The invention relates to a processor, in particular to a method and device for optimizing read and write operation performance. Background technique [0002] Virtualization technology is a very important technology in computer technology. Through virtualization technology, multiple virtual machines can run simultaneously on the same computer hardware, and each virtual machine runs an operating system. Each operating system can run its own applications independently of each other, making the operating systems unaware of each other. However, when the number of virtual machines is relatively large, the performance of different virtual machines for reading and writing operations on the cache buffer (Cache) will affect each other, because the Cache needs to process the read and write requests of multiple virtual machines at the same time, and these virtual machines The visits have their own characteristics. For example, the application program running in ...

AI Technical Summary

Problems solved by technology

However, on the one hand, for a small virtual machine, the virtual machine may run on processor 1 in the last time period, and may run on processor 2 in the next time period; on the other hand, for a large virtual machine, A virtual machine may run on multiple processors at the same time

Therefore, the existing technology cannot identify which virtual machine is sending the read and write request
