It is known that increasing data locality is a good way to benefit from CPU caches. There has been some effort from the IBM���s JVM crew that aligns some frequently accessed variables at a particular offset to improve accesses. Would this approach works in Pharo? 

Other similar situation: will the expression ���Object new yourself��� be faster if the object (i.e., result of Object new) is physically close to the class Object in memory?

Cheers,
