Abstract

The invention provides a method and a device for improving video image access speed, equipment and a medium. The method comprises the following steps: acquiring the number of operation units and the number of CPU cores in a video image access system; receiving an access request containing a to-be-processed service, selecting a corresponding number of operation units and a corresponding number of CPU cores to execute different load strategies according to different types of the to-be-processed service, when the to-be-processed service is detected to be a video image access service, using the operation units not greater than the number of the CPU cores to disperse the load, and distributing the specified load to the corresponding CPU core for video image access processing; and when the to-be-processed service is detected to be the auxiliary service, dispersing the load by using the operation unit with a preset numerical value according to a concurrent distribution principle, and ensuring the concurrent auxiliary service to be dispersed to a part of the CPU cores to be processed. According to the invention, the concurrency and migration overhead of a large number of continuous time slice operation units is avoided, and the request response, the processing speed and the concurrency amount in the video image access system are improved.

Description

technical field [0001] The present application relates to the technical field of data storage, and in particular to a method, device, device and medium for improving video image access speed. Background technique [0002] When running application software intertwined with different operating units, the CPU (central processing unit, central processing unit) core achieves a multi-core load balancing situation by assigning the operating unit to a specific core through an allocation strategy or a migration strategy. However, the CPU core does not know the operating characteristics of each operating unit. When the operating unit executes business, it may cause migration due to load imbalance, which affects the load distribution of subsequent operating units. For example, in some application software with high concurrent requests, the accumulation of performance loss caused by dynamic load or migration may become a bottleneck for its high concurrent request processing support. ...
