Specify fewer parameters

In general, you can improve copy performance if you specify fewer optional copy parameters.

The following parameters affect the performance of the copy operation:

ERRLVL
FMTOPT
INCCHAR
INCREL
PRINT
SRCOPT

Using the COMPRESS function does not significantly affect performance. You should request COMPRESS(*NO) if you want deleted records in the to-file, for example, when the relative record numbers need to be identical.
