Starwind Free slow iSCSI with ESX 5.1

[robert.labrie]

I've googled this to death for a week. I read the sticky on best practices. I enabled jumbo frames. I'm going crazy.

Storage is running on an HP Pro 6200 running Win2k12. It has a built in NIC (used for vmKernel and VM Network) and a dual Intel Pro/1000 PCIe NIC (using one for storage). Disk is SATA.

Host is an HP Pro 8200. Same NIC setup. ESXi 5.1

Storage network is a cross over cable, no switch involved.

Deploying a 3 GB OVF takes 60 minutes. By comparison, deploying the same OVF to and NFS share on the same box, same disk == 7 minutes. I read about tools like iPerf and others, but don't know how to get it on to ESX (SSH is enabled, I drive Debian for fun and profit). I tried a USB disk (I know USB is slower) in the same tests (iSCSI and NFS) and got the same results. Please help, I'm going crazy!

You did not say anything about StarWind configuration which makes us wonder what you've actually used. What target type? What size and cache policy allocated?
