Look for "cache prefetching" in google and decide if you want to optimize JIT, GC or both Here is some interesting links I found
*Prefetch injection based on hardware monitoring and object metadata: * http://portal.acm.org/citation.cfm?id=996873 *Stride prefetching by dynamically inspecting objects: * http://portal.acm.org/affiliated/citation.cfm?id=781131.781161&coll=GUIDE&dl=ACM&type=series&idx=781131&part=series&WantType=series&title=Conference%20on%20Programming%20Language%20Design%20and%20Implementation&CFID=602113&CFTOKEN=49769441 These articles could be too advanced for initial implementation but useful.

Can you instruct me to know some algorithm for how to use cache miss for optimizing? I am afraid i haven`t seen such paper. Thanks a lot.
