Very slow copying to mounted volume dir. Low I/O?

[atabaeph]

Hi, Guys.
I am newbie in GlusterFS, need some help.
created volume for replication to 11 servers. every server must have same files.
mounted volume to /opt/voiceprints
Tried copy all old voicepints to new dir /opt/voiceprints and it was loo long.
then desided to use rsync.
rsync -av --progress /opt/voiceprints.bckp/verify.kz-kz.8k.male /opt/voiceprints/ | pv

/opt/voiceprints.bckp/verify.kz-kz.8k.male this folder only 450MB and it copying more than 1 hour.

Maybe I need to add some configuration?

Do you really want 11 replicas? Are you going to read the data directly from the brick or from the mount? In any case,

Could you provide the file generated in of the format: /var/run/gluster/glusterdumpXXX

setfattr -n trusted.io-stats-dump -v tmp-io-stats_3 /mnt/test

Also could you provide output of the following command before and after running the workload

gluster volume profile <volname> info incremental
