Sysbench测试说明

测试设计

• 测试用实例规格如下：
  • PolarDB-X 1.0（4种规格）：
    • 入门版8核32 GB
    • 标准版16核64 GB
    • 企业版32核128 GB
    • 企业版64核256 GB
  • ECS压力机（1台）：32核64 GB，操作系统Aliyun Linux 2.1903 64位，计算网络增强型
  • RDS（12台）：16核64 GB、MySQL 5.7、独享型
  说明 PolarDB-X 1.0、ECS和RDS都处于同一可用区、同一VPC内。
• 在PolarDB-X 1.0控制台按水平拆分模式创建数据库，选择已经购买的12台RDS。
• 在ECS安装Sysbench，并准备1.6亿数据。如何使用Sysbench，请参见Sysbench 使用指南。
