Hi changwei, i'm sure if you enable quota, the performance will sharply drop. There is a issue to implement glusterfs project quota just like xfs  project quota,  but no progress for a long time.

主题: [Gluster-devel] Glusterfs performance regression with quota enabledHi,

I am using glusterfs-5.6 with quota enabled. I observed a obvious 
performance regression about 30% against a certain vdbench workload[1].

But I didn't set up a hard-limit or soft-limit to any particular volume 
or directory yet, just enable quota.

After disabling features/quota, glusterfs performance went normal.

Is it normal that qutoa will make the performance sharply drop?
