This chapter introduces the performance characteristics of IoTDB from the perspectives of database connection, database read and write performance, and storage performance.
+The test tool uses IoTDBBenchmark, an open source time series database benchmark tool.
## Database connection
-- In the 16C32GB machine, the number of concurrent connections of the IoTDB server can exceed 20,000 times per second.
+- Support high concurrent connections, a single server can support tens of thousands of concurrent connections 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.
-
+- It has the characteristics of high write throughput, a single core can handle more than tens of thousands of write requests per second, and the write performance of a single server can reach tens of millions of points per second; the cluster can be linearly scaled, and the write performance of the cluster can reach hundreds of millions points/second.
+- It has the characteristics of high query throughput and low query latency, a single server supports tens of millions of points/second query throughput, and can aggregate tens of billions of data points 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.
\ No newline at end of file
+- Supports the storage of massive data, with the storage and processing capabilities of PB-level data.
+- Support high compression ratio, lossless compression can reach 20 times compression ratio, lossy compression can reach 100 times compression ratio.

+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，测试工具使用开源的时序数据库基准测试工具 IoTDBBenchmark。
## 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
+- 支持高并发连接，单台服务器可支持数万次并发连接/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
+- 具备高写入吞吐的特点，单核处理写入请求大于数万次/秒，单台服务器写入性能达到数千万点/秒；集群可线性扩展，集群的写入性能可达数亿点/秒。
+- 具备高查询吞吐、低查询延迟的特点，单台服务器支持数千万点/秒查询吞吐，可在毫秒级聚合百亿数据点。
## 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
\ No newline at end of file
+- 支持存储海量数据，具备PB级数据的存储和处理能力。
+- 支持高压缩比，无损压缩能够达到20倍压缩比，有损压缩能够达到100倍压缩比。
