+This chapter introduces the performance characteristics of IoTDB from the perspectives of database connection, database read and write performance, and storage performance.
+
+## Database connection
+
+- In the 16C32GB machine, the number of concurrent connections of the IoTDB server can exceed 20,000 times per second.
+
+
+## Read and write performance
+
+- When the client uses an 8C machine and sets concurrency to 8, the maximum writing throughput of IoTDB on a single-core server can exceed 49,000 times per second.
+- When the client uses a 16C32GB machine and sets concurrency to 10, the writing throughput of IoTDB deployed on 16C32GB server can reach 33.22 million points/second.
+- When the client uses a 16C32GB machine and sets concurrency to 10, the reading throughput of IoTDB deployed on 16C32GB server can reach 67.91 million points/second.
+- When the client uses three 64C256GB machines and sets concurrency to 192, the writing throughput of IoTDB deployed on three 64C256GB servers(1ConfigNode + 3DataNode) can reach 523 million points/second.
+- IoTDB can support aggregation queries of tens of billions of data, and when deployed on a single 16C32GB server, IoTDB can return the calculation results of tens of billions of data in milliseconds.
+
+## Storage performance
+
+- IoTDB supports the storage and processing of PB-level data.
+- Using the ZSTD compression method, IoTDB can achieve a compression rate of 10% for the raw data of the numerical type.

+本章节从数据库连接、数据库读写性能及存储性能角度介绍IoTDB的性能特点。
+
+## 数据库连接
+
+- 在单台16核32GB机器上，IoTDB服务端的每秒并发连接数可超过20000次/秒
+
+## 数据库读写性能
+
+- 客户端使用8核机器、设置并发度为8时，IoTDB数据库在单核服务器处理写入请求的能力最高可达4.9万次/秒
+- 客户端使用单台16核32GB服务器、设置并发度为10，IoTDB数据库部署在单台16核32GB服务器时，写入数据点的处理能力可达3322万点/秒
+- 客户端使用单台16核32GB服务器、设置并发度为10，IoTDB数据库部署在单台16核32GB服务器时，读取数据点的处理能力可达6791万点/秒
+- 客户端使用三台64核256GB服务器、设置并发度为192，IoTDB数据库以集群模式部署在三台64核256GB服务器时（1ConfigNode + 3DataNode），集群的并发写入性能可超过5.23亿点/秒
+- IoTDB支持百亿级数据的聚合计算查询，部署在单台16核32GB服务器时，可在毫秒级返回百亿级数据的计算结果
+
+## 存储性能
+
+- IoTDB数据库支持PB级数据的存储和处理能力
+- 使用ZSTD压缩方式，IoTDB对数值类型原始数据的压缩率可达到10%的级别
