influxdb cluster因为有meta元数据访问（例如写数据前要检查db是否存在，就需要访问meta节点，有http损耗）和一致性要求（例如写一致性，是多个都要求全部写完还是部分写完，取决于consistency参数），所以分布式的influxdb cluster的每个data node节点性能肯定不会高于单机版influxdb，influxdb cluster主要解决集群（多节点存储一部分数据）、高可用问题，通过水平扩展data node完成更大量的数据接入和维护，同时提供配套工具influxd-ctl来维护整个集群。
写入性能则取决于你写的方式，如果不同的数据（例如不同measurement或不同db），从不同节点接入写，性能还是会有叠加提高的
