Description of problem:
Sometime back when I was working on improving gluster performance for hyperconverged vm store workload, I'd seen ~6-8K iops improvement with random read fio test (run from 3 vms hosted on gluster volume).
Even Manoj (cc'd) reported better performance on gluster-block with choose-local disabled.
We're proposing to disable the option in groups virt and gluster-block in light of the above.
Version-Release number of selected component (if applicable):
