BATCH OPERATION -Performance Issue

Hi ,

I am having query with operation of Netwaver gateway.

I am trying to use batch operation for read operation and i get the output for the same also.

While using RFC having table type input parameter.i want to pass multiline input and get want to retrieve the output tables.

I Used below HTTP request

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

GET MM_PUSH_DATASet?$filter=Uname+eq+'KRISH' HTTP/1.1

--batch

Content-Type: application/http

Content-Transfer-Encoding: binary

GET MM_PUSH_DATASet?$filter=Uname+eq+'ABAP_TEST' HTTP/1.1

--batch--

It works fine but after debugging i found that call to database goes twice times.So my query is that if each call goes to database .

Then it will hamper the performance of system.

Do we need to use it in any other way for Table type as input parameter.

Thanks
