Query performace

[mahmudich]

Hi guys!
This question isn’t great importance compare to others but more from tuning point of view.
If I delete unnecessary fields (not calculated and not displayed) from a query would it make a difference in performance? Originally they played debugging purpose.
Thank you

My thinking is, if you don't need them they shouldn't be there.
As to improving performance (like running faster), it should do so.
