Don't confuse bonnie and bonnie++ - they're two different programs and yield
incomparable results.
>From the bonnie++ changelog:
* Reverted zcav to the 1.00a version and then added the code for -u, -g, and
the fix for large numbers of data points. The multi-threaded zcav code
will go into 1.90 (the pre-2.00 tree).
Bonnie++ versions < 1.90 will never again have threading code.
and from earlier in its life:
* Version 1.[0-8]0 will use fork(). Version 1.90 and above will use POSIX
threads and include the concurrant bonnie++ functionality I've been
promising for so long.
