I was going to message via SpiceWorks but I thought this may be a better place per your prior message to me.

I am still have some issues with XenServer and I don't think Citrix pointed me in the right direction. I finally nailed down that I had an issue with the PV NIC when transferring data via SMB shares. I was able to show that it was a Server 2008R2 related issue as my W7 VMs were just fine so the Host, Physical NIC, and Switch were all preforming well with the W7 VM and not the 2008R2 VMs. Citrix had me disable NIC Offloading. I did that Friday and SMB data rates shot thru the roof. Cool right? Well today one of my software packages that uses SMB and SQL calls from the client, a 2008R2 RDS server, would not preform at any usable rate. Worked with the software support folks and would up turning NIC Offloading back on on the application/SQL server and the RDS server and bang the software works ok on the SQL calls but I am back to slow (64 KB) data rates via SMB. So now I have no clue what to do to try to fix this mess.

Host IO is good at 250-300 MBps and all VMs are on local storage. Using XenServer 6.5SP1010. Any Ideas?
