Using RecNo() or RowNo() will impart a performance impact on your load script. I discussed these functions in a previous post where I looked at the output of RecNo vs RowNo.
I recently spotted an unexpected slow-down in a load script, which was caused by using one of these functions. In summary:

– If you must use RecNo(), it may be faster to do this in a direct load
– If you must use RowNo(), it may be faster to do this in a resident load
