Gluster users - Oct 2015 - gluster 3.7.5 low speed on write and heavy load

Yes, now I install the 2 new Slackware machines and I want to setup gluster +
iscsi. I hope that will work as I expected. Do you know to be some issues if I
use multipath to the both gluster servers from esxi?

 From memory, nfs doesn't play very well with vSphere. Are you able to try
iSCSI over gluster?

I use Vsphere and I have replica 2. I share the image via gluster nfs-fuse.I
have 2 dedicate LANs one to esxi and another for gluster cluster replication
thats why I have 120MB/s when I create a new file onto the gluster cluster. But
when I try to use that file like vmdk, the speed drops to ~20-40MB/s.

But if I try to mount an raw file image with losetup, or use vmdk files, and if
I write to them, the speed is 20-40MB/s and I see 12 load on linux.

What VM hosting are you using? KVM/Qemu? vSphere?

How is the image shared out? gfapi? nfs?

Not sure, bit outside my expertise there :) Would multipath just present
you with fail over or would it actually involve esxi writing to the vm
image on both gluster nodes simultaneously?

If the later, vest answered by the devs.
