Well some clues are in http://www.smalltalkconsulting.com/papers/GCPaper/GCTalk%202001.htm See the "Squeak Memory Layout" page But really you have to have an understanding of how the GC behaves, and then the various parms (which aren't in the 2001 paper). then some Sunits, and generate charts like slide 92, then decide how to alter behaviour. Having Sunits is a important criteria since it then tells you if changes are impacting time to run in a meaningful way, since altering the values can have a negative effect. -- =========================================================================== John M.
