I have created couple of variables of type SQL and they are executed in one of the Virtual Users (say VU1). When I do check Virtual User of VU1, then the SQL is executed and the CSV files are created to be used in the script. This is expected behavior.

I have another Virtual User (say VU2) and I am not using that variables (SQL based) in this script.. When I do check virtual user, it still creates the CSV files by firing the query into the DB. This is impacting the performance. Is there anyways of avoiding this?
