思路：

隊(duì)列使用說(shuō)明：

　multiprocessing.Queue()#用于進(jìn)程間通信，單主進(jìn)程與子進(jìn)程無(wú)法通信（使用進(jìn)程池時(shí)盡量不要使用這個(gè)） 　multiprocessing.Manager().Queue()#用于主子進(jìn)程通信，通過(guò)進(jìn)程池（pool）創(chuàng)建的進(jìn)程可以數(shù)據(jù)共享 　queue.Queue()#用于線程間通信，同一進(jìn)程內(nèi)的數(shù)據(jù)可以共享

1.從數(shù)據(jù)庫(kù)里獲取待支付的訂單

2.將獲取出來(lái)的數(shù)據(jù)添加至隊(duì)列（queue.Queue()），并在函數(shù)中返回消息隊(duì)列的長(zhǎng)度

3.根據(jù)隊(duì)列長(zhǎng)度創(chuàng)建對(duì)應(yīng)的線程數(shù)量

4.把創(chuàng)建的線程放在list

5.依次啟動(dòng)

6.最后等待主線程執(zhí)行完結(jié)束，統(tǒng)計(jì)函數(shù)運(yùn)行時(shí)長(zhǎng)

代碼如下

總結(jié)：親測(cè)運(yùn)行時(shí)間還是會(huì)快很多，單線程支付100個(gè)訂單四十幾秒的樣子，多線程運(yùn)行不用join2.x秒，用join八秒的樣子，還有很大的優(yōu)化空間，因?yàn)檫\(yùn)行時(shí)會(huì)創(chuàng)建100個(gè)線程

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持好吧啦網(wǎng)。
