iozone - how to to specify output in MB/sec isntead of KB/sec?

I can't seem to find what the argument for that is. The output is in KB/sec but that generates super huge numbers that are harder to interpret especially given there is no comma separator for thousands. Is there a way to make it output in MB/s or even GB/s instead?

You forgot to tell what application you have in mind.

Not sure what you mean. It's just a program to benchmark disk/volume performance. I'm just looking for a way to tell it to display results in MB/sec instead of KB/sec so it's more readable.

If it doesn't offer the alternate scaling, you are at liberty to do it yourself on the output. awk, perl or any number of other languages.
printf supports a modifier that will even add the (locale dependent) thousand separator for you.

Taking care of invariant rows and/or columns, along with column alignment would probably cause the most grief.

Well was hoping not to have to do that, but if I had to automate it then it would not be an issue. I guess I'll just deal with having to manually figure it out it's not like it's a tool I use that often. I was benchmarking various raid arrays and it was just a pain as it's harder to quickly figure out what the readings are when glancing at lot of results
