Problems solved by technology
[0006] When there are multiple QEMU processes or other processes on the physical server at the same time, because the I / O of the VM is bursty, the threads of librbd will migrate between multiple cores of the CPU, making the cost of thread logical core migration relatively low. high, reducing the I / O performance of the storage system, the present invention provides a method, device, equipment and product for improving the performance of the storage system

The invention provides a method, a device, equipment and a product for improving the performance of a storage system. The method comprises the following steps: querying the configuration of a physicalserver CPU; selecting a bound logic core according to the configuration of the CPU; creating a thread, and binding the created thread with the logic core of the selected CPU; when the threads are scheduled, the threads are distributed to the bound CPU logic cores. And the cost of migration of the thread among multiple logic cores is reduced, and the performance of the storage system is improved.The created thread is bound to the specified CPU logic core, and the thread is allocated to the specified CPU logic core according to the core binding strategy when the operating system schedules thethread, so the overhead of thread migration is reduced, and the performance of the storage system is improved.
Description
technical field [0001] The present invention relates to the technical field of storage system performance improvement, in particular to a method, device, equipment, and product for improving storage system performance. Background technique [0002] Server virtualization can convert physical resources into logically manageable virtual resources, integrate multiple logical servers into one physical server, and achieve the purpose of running multiple virtual environments at the same time, while reducing server costs and making it easier , More secure server management. [0003] QEMU-KVM is a commonly used solution for server virtualization, especially for private cloud scenarios built with OpenStack. KVM provides virtualization of CPU and memory in kernel space, and QEMU virtualizes hardware I / O in user space. When the I / O of the VM operating system is intercepted by KVM, it will be handed over to QEMU for processing. When QEMU is connected to a distributed storage system, i...
