You may also want to check sharding (currently in beta with 3.7) where large files are chunked to smaller fragments. With this scheme, self-healing (and rolling checksum computation thereby) happens only on those fragments that undergo changes when one of the nodes in a replicated set is offline. This has shown nice improvements in gluster's resource utilization during self-healing.
Does it effect read speed and random i/o? I guess that would depend on the methodology used to calculate shard location for a given block. Could be quite interesting on top of zfs, love to test.
