**！！！非官方数据，此压测数据为server端redis模式重构过程中，中间过程的测试数据。！！！**  
**测试目的**：  
在server端redis模式重构期间，测试server端不同的存储数据结构的性能差异，以对部分代码重构提供参考依据。  
主要测试：

*  1.develop分支，db模式，mysql；
 *  2.1.3.0版本，redis模式，lock string结构，session string结构；
 *  3.合并lock 重构pr之前，redis模式，lock string结构，session string结构；
 *  4.develop分支，redis模式，lock hash结构，session string结构；
 *  5.develop分支，redis模式，lock hash结构，session hash结构；

**声明：**  
***本测试数据，受限测试机，服务器，中间件配置，网络因素，以及技术选型，业务场景，仅仅代表个人压测数据，不代表实际生产部署的性能。重点在于显式几种结构下的对比差距，没有任何绝对性能参考依据。测试使用的部分代码来自于未被合并的pr，部分pr不一定会merge到主干！！！因此，数据不具有稳定版本的性能参考意义。请复制黏贴党不要断章取义！***

**场景**：order服务 - > storage服务 -> account服务  
每次请求修改数据为  
order服务 insert 1条 - > storage服务修改5条 -> account服务修改1条。  
**注意**：storage表中只有5条数据，account表中1条数据。此测试场景，并发请求的数据完全相同，每一个请求，都会出现锁冲突，且由于并发较高，会造成严重的全局锁冲突，重试，超时。  
**工具**：jmeter  
**测试项目：**[springcloud-eureka-feign-mybatis-seata][]  
**配置**：均默认配置，未做调整；  
**部署**：seata windows10本地启动  
redis 阿里云 1核1G docker启动  
mysql 阿里云 1核1G docker启动  
**结果**：数据采用95%Line 3次平均值：
