The app server remote datamodule threading model is MultiInstance / Apartment,
and I connect to SQL server using ADO.
When a client connect to the app server and call a time consuming database query interface, then other clients all blocked until the query finished.
I have tried to connect using DCOM connection and Socket connection, same thing happens.
It seems that all job are queued by midas app server, and the server services client access one by one.
Why this happens? How to solve?
