Hi Carlo, I'm very interested about a new study about performance against ZFS by using multiple clusters. The best would be one cluster per disk to see how much improvement we have following this approach.
We know we still have some non necessary locks in the PLocal Storage & DiskCache layers that will not allow to squeeze multi-core at the maximum, but it's something Andrey is working now for the 2.0.
