ESXI All In One NFS Performance Issues

I have been browsing the forums for a couple years, and have gleaned quite a bit of information from here. I wanted to start off with an odd issue that I have ran into since switching ESXI 5 to use an NFS share that is virtualized on the same host.

I have the following hardware in this machine.
2 x Opteron 6128's
1 x Asus KGPE-D16
8 x 4GB Corsair Vengeance 1600Mhz
4 x 8GB Corsair Vengeance 1600Mhz for a total of 64 GB of RAM.
1 x ASUS PIKE 2008 flashed to IT mode for passthrough
8 x ST3000DM001 3TB Seagates
1 x 850 Watt Corsair Power Supply

I am seeing sequential reads of 788MB/s and sequential writes of 375MB/s on my last test with Bonnie++.

I have been able to get sequential read speeds with CIFS and NFS from a Windows 7 machine that is not running on the ESXI host, ranging from 100-115 MB/s.

I have Synchronous writes disabled on the ZFS share I am using to run VM's. I noticed immediately upon switching my VM's has been terrible. I recently ran a DD from the ESXI shell to the NFS share, and found that it took 46 seconds to write a 4MB file.

I am currently using the E1000 driver on the OpenIndiana machine due to concerns with the VMXNET3 driver causing performance issues.

I also ran a zpool -iostat during the DD, and was seeing write speeds on the array of less than 260Kbps.

I should also note that I am running the ESXI install from a USB drive, in case that could lead to the performance issue.
I briefly also tried ISCSI to see if it was an issue with NFS, but had very similiar results.

Has anyone encountered an issue like this before?
 
Your post is kind of weird. I have no idea what your complaint is. You're not happy with dd speed? Running dd in the ESXi console is not a good test, busybox is a bottleneck
 
Sorry about not getting to the point, essentially, even file copy's through the vsphere client from a local SSD on the ESXI host, to the NFS share, are not even coming close to 1 MB/s. I am just trying to determine why I can get 90+ MB/s accessing a share from a VM, but the host is averaging 1% of that.
