You misinterpreted me, (or I didn't make myself clear). I don't expect 
it to be faster in all cases, but I wouldn't expect to see any cases 
where a shared heap performed worse than without it. Maybe on par, but 
not worse. Hence my question, will there be cases where using a shared 
heap will degrade performance?
