Problems solved by technology

[0003] From the perspective of software processing, the processing performance of the system often decreases rapidly with the increase of processing traffic and the increase of processing processes.
There are many reasons for performance degradation. From the perspective of system calls and thread switching overhead, the reasons include the following points: ①Multi-thread processing performance is not linearly related to the number of threads, and the overhead caused by high-frequency switching between threads will cause The reduction of processing performance; ②The system interrupt 0x80 and the switching between user mode and kernel mode have certain overhead, and the impact brought by frequent system calls is particularly obvious; Reduced performance; ④ not fully utilizing the CPU resources of the multi-core platform

The invention optimizes the factors affecting the performance of data processing in a targeted manner, improves the processing efficiency of the program, and can quickly reuse different business requirements, reduces the difficulty of development and shortens the development cycle.

Description

technical field [0001] The invention relates to the field of mass data processing, in particular to a multi-task development model and method based on a multi-core platform. Background technique [0002] Massive data processing platforms usually have high requirements on system processing performance, and need to process network data quickly and efficiently. With the development of technology, the processing performance of hardware is getting higher and higher, and resources such as multi-core platforms and large-capacity memory have greatly improved the efficiency of massive data processing, while the bottleneck of system processing is gradually inclined to processing software. [0003] From the perspective of software processing, the processing performance of the system often decreases rapidly with the increase of processing traffic and processing flow. There are many reasons for performance degradation. From the perspective of system calls and thread switching overhead, ...
