comment Disk IO Performance Difference — Hyper-V / CSV — Guest vs Host
I decided to perform a packet capture with my original tests and found some interesting differences. When performing the random r/w test from the VM, a good amount of the traffic captured was listed as using iSCSI protocol which makes sense since my hosts use iSCSI to connect to the storage. However, when performing the test from the host directly to the iSCSI connected volume, I see very little iSCSI protocol traffic. Instead I see a lot of TCP traffic from port 3260. (FYI -- That port is also iSCSI but displays differently it seems.) Not sure if this is relevant.

@EliadTech -- (1) The test from the host with the VHDX mounted gave numbers in line with the test from the host directly to the volume. That seems to point to a Hyper-V/VM issue. (2) Oddly enough, changing the test to perform sequential read/write gave very close (but not veyr good) numbers. Testing from both the host and the VM gave about 7k/3k read/write IOPS.

1) I am positive nothing else is running. 2) You are suggesting that I create a vhdx on the local disks on the host as opposed to putting it on the cluster? I can test that. 3) As you can see in the config file with the rw=randrw, the testing is random and not sequential.

Never heard of Negative source journaling. Will have to look into that. Thank you John.

@JohnBreakwell -- That was it. Needed Anonymous Logon...cannot believe I missed that one. Would have thought there would be some sort of permission denied message someplace but maybe not. Please move your comment to an answer so I can mark it. Thank you.

comment IIS 8 and MSMQ over HTTP without WCF
John -- Thank you for that. For some odd reason, it was rendering differently than actually typed. I had to mark that as "code" in order for the proper value to be displayed. (Although preview does/did render properly.) Does SO do something special with text that has HTTP in it?
