Problems solved by technology

When performing software performance debugging, because the debugging code is embedded in the software, the execution time of the next-level subtask is prolonged, which causes a delay in the response time to the upper-level subtask request, or even fails to respond

Abstract

The invention discloses a management method and a management system for a software performance test based on a distributed virtual machine system. The method comprises the following steps that: in response to a debugging state of a software system perceived to a current virtual machine, the system time of the current virtual machine is controlled; in response to intercepted data packets sent to the current virtual machine by other virtual machines, the reference time and the added system time for sending the data packets by the other virtual machines are extracted from the data packets sent to the current virtual machine; the time of the data packets expected to be received by the current virtual machine is calculated according to the system time and the reference time when the other virtual machines send the data packets and the reference time during the data packet interception; and whether the data packets are forwarded to the current virtual machine or not is determined according to comparison results of the time of the data packets expected to be received by the current virtual machine and the system time of the current virtual machine during the data packet interception.

Description

technical field [0001] The present invention relates to the management of software performance testing, and more specifically, to a management method and system for software performance testing based on a distributed virtual machine system. Background technique [0002] Software performance debugging is an important part of software quality control. The purpose of software debugging is to check out potential flaws in software implementation or configuration, and improve the system on this basis. Software debugging focuses on a series of diagnostic information reflecting the detailed running state of the software (such as the iterative calling sequence of multiple related functions under a complex function). In order for the system under test to generate these diagnostic information, it is necessary to embed a series of debugging codes (instruments) for generating diagnostic information into the system under test before running. The embedding of these codes will increase the...
