inserting data slow when insert data in bulk

**environment:**
version: 1.0.0
deployment: all in one, one confignode, one datanode
host: cpu: 16core, mem:16G, disk: ssd, os: ubuntu 22.04
client sdk: python, use normal tablet

**background:**
the measurements number of a batch of data is huge, in my usage scenario, sometimes it is 200,000.

**experiment:**
I tested the insertion performance.
Insertion takes 2.5s-4s when all measurement points are inserted in one database and the measurements number of a batch is 200,000.
Insertion takes 0.3s when all measurement points are inserted in 10 databases of one instance and 10 threads, one thread insert 20,000 measurements once.

I looked at the usage performance of host, cpu only used under 200%, memory is still remain, disk io is 8MB/s.
None of this is a bottleneck. so i strace the process:

```

79.04 52.355396 1545 33867 4478 futex

0.02 0.013909 5 2750 write

```

in strace log, many lock timeout:
```
335339 16:00:27.993273 futex(0x7f1b240f6028, FUTEX_WAKE_PRIVATE, 1) = 0 <0.000011>

```

so i traceing java process use jstack, but I can't read the contents, but there is code related to locks.

**question:**

1. In cases where there are so many measurement points, How do I need to optimize it? I look at the documentation and there are too many configuration parameters. https://iotdb.apache.org/UserGuide/Master/Reference/Common-Config-Manual.html
2. Can it improve performance, if i use cluster mode.

El informe no menciona archivos ni pruebas del repositorio; comienza reproduciendo la inserción masiva con el despliegue de IoTDB indicado, el cliente de Python, la salida de strace y la captura de jstack. Lee el Common Config Manual enlazado y compara ejecuciones con una sola base de datos y en modo clúster. Se considerará completado cuando se identifique el bloqueo o la configuración limitante y se documente una optimización verificada o un resultado de rendimiento del clúster.
