Glusterfs Ver: 3.7.6

1) Currently I am using disperse  volume  and its performance is not
 So I tried  "sudo gluster v set ec-vol performance.client-io-threads on"
(as per https://bugzilla.redhat.com/show_bug.cgi?id=1349953)

on the volume . But  I am getting
Connection failed. Please check if gluster daemon is operational.  error.

volume info

Volume Name: ec-vol
Type: Disperse
Volume ID: 66d9f9e9-8bbd-46d8-b491-5b3e48219ee1
Status: Started
Number of Bricks: 1 x (4 + 2) = 6
Transport-type: tcp
Brick1: jk:/home/jk/gluster/brick1
Brick2: jk:/home/jk/gluster/brick2
Brick3: jk:/home/jk/gluster/brick3
Brick4: jk:/home/jk/gluster/brick4
Brick5: jk:/home/jk/gluster/brick5
Brick6: jk:/home/jk/gluster/brick6
Options Reconfigured:
performance.readdir-ahead: on

Attached  the  log.

How  to resolve this error ?

2) If I replace  the Erasure code algorithm  in the EC  with a simpler one
, will  it  give a better performance ?  What is  the real bottleneck ?

Best Regards
