PolarDB-X 1.0和RDS性能对比之吞吐量对比（三）
2024-05-14 15:59:41
测试环境：
PolarDB-X 标准版：16C64G(1台)
RDS MySQL5.7： 16C64G(4台)
ECS 压测机： 8C16G(1台)
sysbench 0.5
通过前期的测试，PolarDB+RDS测试中 PolarDB-X+RDS x4性能最好，接下来进行两轮测试，直连RDS和 PolarDB-X+RDS x4两种环境下，分别进行线程数为200、500、1000、2000、5000的测试。
第一轮测试：直连RDS
测试一：线程数200

不同线程数下两种环境的QPS表现：
不同线程数下两种环境的响应时间(ms)：
可以看出：
两轮测试过程中，直连RDS QPS比PolarDB-X + RDS x4要高的多，差不多是两倍的关系，我分析原因为：OLTP场景下，索引选择良好，单次SQL消耗时间并不长，而 PolarDB-X对会话的路由时间消耗太多，以至于QPS跑步上去。
而且响应时间， 直连RDS也比PolarDB-X + RDS x4要快，线程数越多，差异越大。
直连RDS测试过程中，CPU使用率和IOPS监控：
PolarDB-X + RDS x4环境下 CPU使用率和IOPS监控：
可以看出：
两轮测试中，直连RDS要比 PolarDB-X + RDS x4 CPU和IOPS使用率都高，我分析有两方面原因：
1)PolarDB-X + RDS x4将数据分散在4个RDS实例中，因此CPU和IO消耗全部分散到各个实例中；
2)PolarDB-X + RDS x4环境中，QPS本身就比直连RDS要低，资源使用率没有上去。
通过这两轮测试总结：
1)相同线程数，PolarDB-X下RDS的资源消耗更低，因为资源消耗分散到了不同RDS节点；
2)相同线程数，直连RDS要比 PolarDB-X+RDS吞吐量更高，rt更低；
3)针对于OLTP这样的场景，如果应用系统并发量不高，可能还不如用RDS更舒服。
