It will be less efficient, indeed, because the GC will take longer because it will also traverse the part of the heap that used to live in the purespace. This effect is more noticeable in sessions where the heap is small (and hence what used to be purespace represents a more significant fraction of the total) and becomes unmeasurable once the heap becomes large enough to dwarf the purespace. But please note that we have all been living with exactly this inefficiency ever since we started using pdump. So while it will be slightly less efficient, it will still be as efficient as what we get with pdump, which I believe we all consider as acceptable. Stefan
