DYNAMIC THREAD POOL ADJUSTING TECHNIQUE

摘要

PROBLEM TO BE SOLVED: To adjust thread pools within a multithreaded server based on statistics observed from a server's inbound working load. SOLUTION: For various types of requests processed by the server, an execution time and a waiting/queue time are tracked. A plurality of logical pools of threads are used for processing the requests and an inbound request is sent toward one selected from among the pools, so that the requests with the same time requirement are processed by threads within that pool. The number and size of the thread pools are adjustable according to a program and a distribution calculation (i.e., determination as to which of the inbound requests should be allocated to which of the pools) is a determination based on the program. In a preferred embodiment, only one of those variables is adjusted at a time and the result is monitored to determine whether effects are positive or negative. COPYRIGHT: (C)2004,JPO&NCIPI
