Abstract

The invention discloses a print frequency control method, which comprises the following steps: A. setting the threshold value of CPU occupation rate at the print information output time; obtaining the occupation rate of present system CPU; B. judging whether the occupation rate of present system CPU exceeds the threshold value; stopping outputting the print information if yes; outputting the print information if not. The invention improves the system stability when the occupation rate of present system CPU is high, which guarantees the system stability.

Description

technical field

[0001] The invention relates to a control technology of printing frequency, in particular to a method for controlling printing frequency. Background technique

[0002] Printing is very important in many communication software modules. Through the printed information, we can easily locate the fault in the system; at the same time, the printed information is also very helpful for us to observe the running process of the code. However, if the printing frequency is not well controlled and there are too many information to be printed at the same time, the printing frequency will reach a high level, which will affect the stability of the system.

[0003] For example, when the system business is busy, the central processing unit (CPU) has a relatively high occupancy rate. If there are too many printing information to be processed at the same time, the CPU will temporarily interrupt the processing of certain lower priority services. Processing, switch to the proces...
