I have been working on execution time for my Smalltalk implementation and am having trouble getting repeatable times. I am using a script from a new launch of java with all apps turned off. I run the target code 10 times to let Hotspot do its thing. What I see are times of great performance and times
that are 30% slower after they stabilize. Since I am trying fine grained changes in method lookups etc it makes it difficult to determine if what I try helps or hurts. Any suggestions on how to do a better job? I am using a core 2 duo with snow leopard. thanks mark
