What performance tuning experience do you have? Explain


What performance tuning experience do you have? Explain

 We can do performance tuning experience by a making a  note of time taken to execute for every task and process in the ETL life cycle i.e, Making  a note time taken by source , transformations, destination loading  and used as many variables for sql task and connection manager. Like I used to create a variables where I can store all the sql queries there and save the connection manager  in variables so that the package will be more  faster. I used only used column not all the columns of the data by writing a where clause in sql . For data conversion I used advanced editor in source rather then using data conversion transformation. Etc.
