Re: Performance drop when upgrading from 3.8 to 6.5

Dear Rafi, all,

please find attached two profile files; both are profiling the same command:
```
time rsync -a $SRC root@172.23.187.207:/glusterfs
```

In both cases, the target is a Ubuntu 16.04 VM mounting a pure
distributed GlusterFS 7 filesystem on `/glusterfs`.  The GlusterFS 7
cluster is comprised of 3 identical Ubuntu 16.04 VMs, each with one
brick of 200GB.  I have turned ctime off, as suggested in a previous
email.

In the case of file `profile1.txt` (larger file), $SRC is a directory
tree containing ~94'500 files, collectively weighing ~376GB.  The
transfer takes between 250 and 300 minutes (I've made several attempts
now), for an average bandwidth of ~21MB/s.

In the case of `profile3.txt`, $SRC is a single tar file weighing
72GB.  It takes between 16 and 30 minutes to write it into the
GlusterFS 7 filesystem; average bandwidth is ~60MB/s.

To me, this seems to indicate that, while write performance on data is
good, metadata ops on GlusterFS 7 are rather slow, and much slower
than in the 3.x series.  Is there any other tweak that I may try to
apply?

Thanks,
Riccardo
