Absolutely. It will be just a fifth iops number to combine with the other 4 IOPs numbers
(mdtest create easy/hard and mdtest stat easy/hard) using geo mean.
Figure out the number of files created by the four produce phases: n. Then divide that
by wall-clock for the find command: w. Then the 'find' IOPs is n/w.
My concern is that it will be so slow that people will give up and not run it.
I don't see why that would be true? For Lustre at least, readdir() and stat() are
about 2x as fast as creating files.
