David,

Since there have been a bunch of threads recently on Octave performance,
could you benchmark this change to see if there are any performance issues
in the ordinary case where BOUNDS_CHECKING is disabled?

As jwe pointed out, asserts are always enabled in Octave, so I need to know how to add a new flag telling Octave whether to reference-check.  Once I've done that, I'd be happy to benchmark the result.  Is there a standard set of Octave benchmarks I can use?

David,

We don't have a formal performance benchmark.  But, we often use 'time make check' from the shell.  This should be good enough to know whether we should be concerned or not.

​I suspect that "make check" is heavily dominated by disk IO.
