[Gluster-users] high load when copy directory with many files

[Adrian Quintero]

Have you tried tuned profiles? random-io
what type of storage are you using, spinning or SSD?


Just guessing here,  if you can provide a bit more details maybe someone
has already ran into this and has found a solution


regards,

Adrian Quinter
