Well, I did try it. I thought I saw 50 million mentioned in this thread, but all I can actually find now is "millions." I couldn't get enough storage for 50 million, but I did try it for 10 million.

These were run under Hercules - 18.45 seconds to write 10,000,000 records to a data set, 1.06 seconds to "write" to DD DUMMY. The loop overhead was 0.10 seconds.

The program wrote a fixed record, so there was no record preparation time, so a real program will show higher times
