Dear fio developers,

Thanks for the very good application, but may I suggest that the size= 
option controls only the size of the files used for the test (in 
particular random r/w tests), while there should be another option 
totaltransfer= which controls how long is the test? And/or a walltime= 
option to make the test length time based... even better!

Currently we either are hit by short seeks (size= small) or have to wait 
for impossibly long tests uselessly (size= large).

Thank you

What about just adding a runtime= setting to shorten the run? Use the
full size, but put a cap on runtime.
