Problem is as follows: I should to import some data from .txt files using BULK INSERT, then parse those data into proper columns in some staging table. Executing stored procedure in QA needs only few seconds to complete, but, using scheduled job to execute T-SQL having "exec procedure_name param1,param2" takes much more time to complete. I noticed that another one job executes simultaneously during my job execution, but this job doesn't affect the same objects as "my job".
What can cause slow execution with programmed job?
