[Gluster-devel] Confused on AFR, where does it happen client or server

[Anand Avati]

if it does parallel IO on multiple files, then the scheduler will make a
difference. since this is a setup with only 2 servers and 2 copies of files
are there, unify is not really needed. I need to check with krishna what is
the current status of AFR read load balancing (which will play the main role
here). so using the 'option read-subvolume local-posix-volume' (overrding
read scheduling) will make server AFR read performance equal to client side
AFR since scheduling reads on server side will make reads have 2 hops.
