[Gluster-users] Optimal shard size & self-heal algorithm for VM hosting?

Hey guys,
 I keep seeing different recommendations for the best shard sizes for VM
images, from 64MB to 512MB.

What's the benefit of smaller v larger shards?
I'm guessing smaller shards are quicker to heal, but larger shards will
provide better sequential I/O for single clients? Anything else?

I also usually see "cluster.data-self-heal-algorithm: full" is generally
recommended in these cases. Why not "diff"? Is it simply to reduce CPU load
when there's plenty of excess network capacity?

Thanks in advance,
Doug
