(I think that is what is used for the > oldest generation.) If we have a lot of stable memory, say 1GB in the oldest generation, then we need another 1GB for to-space to run the copying GC. A compacting GC tries to move all live objects in the 1GB area to "one side", freeing up the holes left behind by dead objects. That needs much less extra memory, I guess a few MB. It may be a bit slower, though. Helmut _______________________________________________ cmucl-imp mailing list [email protected] http://lists.zs64.net/mailman/listinfo/cmucl-imp
