Yes.  That's the theory.  In theory the SDK has better code than the
Fedora (and that may have been true in FC7).  I'm not sure that's
still the case.  The numactl* stuff doesn't work on the PS3, so it
doesn't matter.  I haven't looked to see if they're really installing
a cell optimized blas or not.  Last I checked, oprofile on F8 was
better than the SDK at least when running on the QS21 blades (no
hypervisor).  You'll have to see how oprofile works on the PS3.
There's also another ps3 specific performance tool in Geoff's stuff,
though I don't remember what it's called.
