Abstract

The invention provides a thread number evaluation method and device, and the method comprises the steps: obtaining parameter information of a to-be-evaluated server in a retrieval system, and the parameter information comprising the average flow and the average processing time; establishing a relational expression between the parameter information and the performance parameter information; whereinthe performance parameter information comprises the total number of requests on the server, the number of requests to be processed, the average waiting time and the average response time; wherein theperformance parameter information and the thread number of the server have an association relationship and change along with the change of the thread number of the server; obtaining the thread numberwhen the average response time meets the expected response time by combining the relational expression, the parameter information and the queuing model; determining the thread number as the thread number of the server, so that the thread number can be determined by combining the parameter information of the server, the relational expression between the parameter information and the performance parameter information and the queuing model, the thread number does not need to be adjusted for multiple times, the time period is short, and the stability requirement of the retrieval system can be ensured.

Description

technical field [0001] The invention relates to the technical field of retrieval, and in particular, to a method and device for evaluating the number of threads. Background technique [0002] At present, ultra-large-scale retrieval systems, such as Google, Baidu, etc., usually consist of a large number of servers in clusters to provide information retrieval services, and each server deploys retrieval programs with corresponding functions. The number of threads of the retrieval program directly affects the response speed of the retrieval system to user requests. The current method for setting the number of threads of the retrieval program is to first set an initial number of threads, and then adjust the initial number of threads several times according to the actual operation of the retrieval system until the response speed meets expectations. [0003] In the above solution, multiple adjustments to the number of threads are difficult to ensure the stability requirements of t...
