Description
to be able to write to OST objects the client needs to lock them with extent locks. those are synchronous RPC(s) which slow down workloads like untar where relatively small amount of data needs few sync RPCs (metadata, locks, etc).
the client can be given an exclusive access to layout information making OST locks optional. this can improve small file performance.
