Gluster users - Feb 2017 - Quick performance check?

Hi,

I ran some benchmarking on SSD enabled servers, 10Gb connected, see
the file attached.

I'm still looking at GlusterFS as a persistent storage for containers,
and it's clear it's not going to compete with local file system
performance.

Cheers,
Vladimir

Well that's kind of a given, with the standard rep 3, you're doing a
sort
of RAID 5 across the network. However depending on your use case & setup,
you *can* get performance boosts akin to RAID 10 setups, multiplied bu the
number of nodes/bricks in the cluster.

I couldn't find the particular doc, but I've seen some ludicrous
throughputs from configs using multiple nodes running SSDs in RAID 10 and
peering over Infiband.
