| # 性能特点 |
| |
| 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 [iot-benchmark](../Tools-System/Benchmark.md)。 |
| |
| ## 数据库连接 |
| |
| - 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 |
| |
| - 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 |
| |
| - 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。 |
