So I have a support request into VMware for this but could really use some suggestions.
I noticed some disk write slowness to the main R630 server running all the Server 2012 servers and discovered it was because they put a H310 with no cache and it was supposed to be a H710. I upgraded it over the weekend to a H720P but the slowness continues on the other host running the vdis.
I read some posts where people say that the desktops are slow because they set them up with non-persistent hard drives. The virtual desktops are linked clones with non-persistent hard drives but they are assigned the same desktop every time and I never refresh or recompose the desktops. They act just like regular desktops and all windows updates, patches and applications are installed right to the individual desktops.
I know this isn't best practice so I set up a test pool with a linked clone and remove the non-persistent hard drives and ran a few tests and the performance is still really bad. Even on a single stand alone Windows 7 desktop through the console the performance is bad.
The CPU's on the performance test rates like it is a core 2 duo from 15 years ago.
Like I said in my original post I have a test environment running old E3 Super micro servers and the same setup is blazing fast. Linked Clones - Persistent hard drives running view persona. I feel like something is wrong with the dell R620 server. It has newer E5 2Ghz chips in it and it is dog slow with 10 desktops.
Any help would be appreciated.
Thanks, J
