Can you also describe the rough changes in terms of time and (peak) memory used? As replied to patch 5/5 it's probably not too important to get the perfect reference setup for evaluating this, but to have one that isn't an obvious extreme (no snapshots, the same snapshots a hundred times, ...) and describe that setup. It might be also nice to mention that this is in preparation to get better cache reuse due to processing snapshots from the same group closely together. _______________________________________________ pbs-devel mailing list pbs-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pbs-devel
