並發測試示例代碼__Java SDK_SDK使用手冊_消息服務-阿裏雲

本文檔介紹了基於Java SDK提供的隊列消息發送以及消費的並發測試Case。

1. 用戶可指定並發度、運行時間；
2. 使用發送總請求數除以運行時間得到QPS；

1. 初始化

在運行目錄創建perf_test_config.properties文本文件，按照如下格式指定參數（其中隊列請先行創建好）：

Endpoint=
AccessId=
AccessKey=
QueueName=JavaSDKPerfTestQueue
ThreadNum=200
TotalSeconds=180

注：

ThreadNum是發送/消費的線程數，MNS具備強大的高並發擴展性能；
TotalSeconds是測試Case運行的時間；

2. 代碼
