模拟出 8 条任务。事务ID为 57、58、59、63、64、65、68、69 的同步时间(分钟)分别为：11、12、13、12、11、12、11、12 。事务ID为 57、58、59、63、64、65、68、69 的同步次数分别为：21、22、22、19、17、5、17、17 。事务ID为 57、58、59、63、64、65、68、69 的同步频率分别为：11 * 60 / 21 = 31、12 * 60 / 22 = 33、13 * 60 / 22 = 35、12 * 60 / 19 = 38、11 * 60 / 17 = 39、12 * 60 / 5 = 144、11 * 60 / 17 = 39、12 * 60 / 17 = 42。得出平均值：(31 + 33 + 35 + 38 + 39 + 144 + 39 + 42) / 8 = 50。理论上的计算公式，进一法取整(事务数量 / 5) / 容器数量 * 60。符合预期 0

在 bash sleep 60 秒 的情况下，很难出现并发锁定的情况。或者增加更多的容器，或者提升执行命令行的频率。设置 bash sleep 10 秒。已经出现并发锁定(防止同一个租户下的用户同步同时在多个容器中执行)的情况。当部署为集群时，已经可以保证同一个租户下的用户同步，在某一时间段，仅在 1 个容器中执行。理论上的计算公式，一个租户的同步时间间隔为：4 / 3 * 10 = 13，结果单位为秒。符合设计预期。总结：部署的容器数量不要超过租户的数量，以防止并发锁定的情况过于频繁。 0
