Abstract

The invention discloses a file reading method and an electronic device. The invention adopts the paging technology to divide the large file into a plurality of pages through the segmentation processing of the large file so that any record in the large file can be accessed randomly during the paging loading in the reading process. The sliding window mechanism is used in the loading process to loadthe file from the next line of the current line of the file quickly, which reduces the time of locating the file line. In addition, the next page is loaded asynchronously in advance. When the number of random records on the current page approaches to the number of data records on the page, the next page is triggered asynchronously, which reduces the violent fluctuation of pressure measurement flowQPS caused by loading documents in the process of pressure measurement. After the page loading is completed, the read-write lock mode is adopted, the read-write permission of the loading page threadis set to read-only, and the read-write permission of the pressure measuring thread is set to write-only, so that the resource contention between the loading page thread and the pressure measuring thread is reduced, and the concurrency between the pressure measuring threads is improved.

Description

technical field [0001] The present disclosure relates to a file reading method and electronic equipment. Background technique [0002] In network technology, it is necessary to perform performance stress testing on the network. Given a parameterized file record, randomly select a record to apply to each request in the stress testing process, so that the stress testing data is diverse and more realistic and close to the real scene. In the parameterized file , the parameter is used to construct a data set. After the data value is replaced with the specified variable value in the request setting, the value in the parameter source will be dynamically replaced with the specified variable value during the pressure application process. [0003] The general method of random parameterizing a file is to read the file into the memory at one time for process sharing, and then randomly select a line of records according to the size of the file line number as the return of the random para...
