Performance tuning of a Fast Load Script- - response (4) by Nishant.Bhardwaj

Thanks a Lot Ulrich  for the Valuable inputs !
I understood that If we can keep  in sync the Source & target tables , the effective bytes  would  be reduced ( as in the case of varchar , the spaces would be trimmed off & in case of chars ,spaces got padded up and increase the length)..
Also in the file layout its better to define the field lengths as *VARCHAR inplace of *CHAR , as it will consider only the effective bytes rather than the max length of the column.
 
Please correct me if I am missing any thing here.
 
Cheers!
Nishant
