### Search before asking - [X] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened I try sqlserver sink, the speed is very slow. The data volumn is 36w， if I use different source ,the result is the same. If i use mysql sink, we can load the whole data in 20s. And I watch the result table for sqlserver , we only insert 1k data into the table in 1s. It seems the batch size doesn't work. So the sqlserver sink has some problem .I also tried different jar lib. ### SeaTunnel Version 2.3.5 ### SeaTunnel Config ```conf sink { Jdbc { url = "jdbc:sqlserver://***:1433;DatabaseName=***;encrypt=false" driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver" database="***" user = "****" password = "***" data_save_mode="DROP_DATA" schema_save_mode="ERROR_WHEN_SCHEMA_NOT_EXIST" generate_sink_sql = true batch_size = 200000 table = "dbo.****" } } ``` ### Running Command ```shell /data/share_storage/seatunnel-2.3.5/bin/seatunnel.sh --config **.config ``` ### Error Exception ```log no exception ``` ### Zeta or Flink or Spark Version zeta ### Java or Scala Version 1.8 ### Screenshots  ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
