# TiDB Sysbench 性能对比测试报告 - v2.1 对比 v2.0 | ||
|
||
## 测试目的 | ||
|
||
对比 TiDB 2.1 版本和 2.0 版本在 OLTP 场景下的性能。 | ||
|
||
## 测试版本、时间、地点 | ||
|
||
TiDB 版本:v2.1.0-rc.2 vs. v2.0.6 | ||
|
||
时间:2018 年 9 月 | ||
|
||
地点:北京 | ||
|
||
## 测试环境 | ||

| DISK | Optane 500GB SSD \* 1 | | ||
|
||
Sysbench 版本:1.1.0 | ||
|
||
## 测试方案 | ||
|
||
使用 Sysbench 向集群导入 **16 张表,每张数据 1000 万**。通过 HAProxy 代理,分别以递增并发数向集群发送请求,单次并发测试时间 5 分钟。 | ||
