RE: Re: Optimizing File I-O in RPG IV/I-Series

Jim,

If you use READ, then try using an OVRDBF prior to calling the program
and specify a value for the NBRRCDS parameter, where:

NBRRCDS = 32000 / physical-file-record-length (rounded down).

and see if that improves things. I assumed an ODP size of 32K, but it
may be 64K or higher, but 32K works pretty well.

Rory

p.s. BLOCK(*NO) would never help, because it turns of blocking, which is
not what you want. Default blocking is normally good enough, but you can
tweak it, as above.
