FreeNAS too slow on Dell R720

[Leandro Soares]

Hello, I decided to resort to the forum as I have a slow problem in my VMs that are connected via iSCSI in FreeNAS with Jumbo Frame enabled.
Hardware:
Dell PowerEdge R720xd
32Gb RAM
04 Disk SAS 06Tb in RAID-10.
01 SSD for FreeNAS 9.10.2 U1
01 SSD for ZIL.
Storage network in lagg0 (LoadBalance + mtu 9000).
VMs Initialized in XenServer 6.2 Storage Network in mtu 9000.
Note: In my case, I only have one vm win server 2012 r2 connected so far.

You will need to provide some specific benckmark results to quantify the throughput. Also I do not understand what you mean by RAID-10, is this for XenServer or FreeNAS? If for FreeNAS, call it by it's proper terminology as it adds to confusion. Also, if this all sits on top of XenServer, how does FreeNAS have access to the hard drives? Be as specific as you can, every detail helps. It could be that someone tells you that what you are trying to do will not work as you desire, or someone may tell you to make a few changes and all will work nice and fast. I've never used XenServer so I doubt I'll be able to offer assistance but if I could get you to give up some more data, it will help whoever is going to offer assistance.

Good Luck
