A little late, but: back when we had Lotus Domino running on z/OS, at one point we converted to ZFS and then converted back to HFS. A newly re-organized HFS isn't bad, and they said performance was better than via ZFS. This is stressing the 're-organized' part. An HFS with lots 'traffic' (delete and allocate of small data sets) over time not only gets bad space utilization, it also gets slower. I cannopt answer you actual space question. At a guess I would say initially it is a 1:1 relation, give or a take 5%. Regards, Barbara Nitz -- Ist Ihr Browser Vista-kompatibel?
