System time consumption test method, apparatus and device, and readable storage medium

Abstract

The invention discloses a system time-consuming test method, which can realize accurate time-consuming test through replicated in-out optical fiber signals of a system to be tested and almost no time difference between the optical fiber signals entering the system to be tested and the replicated optical fiber signals. When a source data optical fiber signal is copied, the source data is basically not influenced, so that the influence on the actual operation of the to-be-tested system is avoided, and the real time consumption of the system can be measured; moreover, data receiving and processing are executed by equipment running outside the to-be-tested system, so that the measurement environment has no influence on resources of the to-be-tested system, accurate testing of the actual running state of the to-be-tested system can be realized, and meanwhile, as long as the network input and output of the to-be-tested system are in an optical fiber access mode. The scheme can be adopted for measurement, and accurate testing of different tested systems can be achieved. The invention further discloses a system time consumption testing apparatus and system and a readable storage medium, and the corresponding technical effects are achieved.

Description

technical field [0001] The invention relates to the technical field of system testing, in particular to a system time-consuming testing method, device, equipment and a readable storage medium. Background technique [0002] In the high-speed programmatic system, the delay / speed test of each module of the system has always been an important method to evaluate the performance of each module in the programmatic trading system. Accurate speed test can accurately reflect the time consumption of each module of the system, and provide accurate optimization direction for system optimization and debugging. [0003] At this stage, due to the development of software and hardware technology, the system time consumption of the programmed system has entered the single-digit microsecond (microsecond) or even nanosecond (nanosecond) level. For example, in the programmed trading system of financial securities products, the market forwarding system has already It can achieve a time-consuming ...

AI Technical Summary

Problems solved by technology

[0006] Since the time consumption of the entire system is already very small, the performance consumption brought by the software testing process itself can no longer be ignored, and additional CPU / memory resources of the system itself are required to execute corresponding functions, which will have a significant impact on the performance of the system itself , that is, the measurement method affects the measurement object itself, the measurement result cannot accurately reflect the performance of the measurement object itself, and the detection accuracy is low; moreover, when measuring the time of entering / exiting the system at the network level of a subsystem / module, this method requires The time stamp of the system must be the time stamp of the same reference system (such as the same server), but there are different situations between the network segment entering the system under test and the system leaving the system through the software, and the time stamps recorded in the system and out of the system are not in the same absolute The time axis, and the time stamps in different reference systems are quite different, which cannot reflect the time-consuming processing of the system itself; in addition, once the system needs to be modified, it is very likely to affect the measurement code itself, which needs to be modified synchronously; in addition, if figure 1 Shown is a schematic diagram of a traditional software processing time-consuming test method. It can be seen that using software to measure time-consuming processing can only realize the time-consuming measurement of the system application layer and cannot count the network hardware layer, hardware driver layer, system kernel layer, and system The two-way traversal time of the four layers of the protocol stack cannot accurately measure the overall processing time of the system under test.
