Poor Hyper-v performance on guest machines
Hi Experts.
I'm having performance issues with our Hyper-v server. I'm not very experienced with HYPER-V so I was wondering if you guys could help me out on this one.
Specs:
HYPER-V Host:
Windows Server 2008 R2 SP1 64Bit (full install)
2x Intel Xeon X5690 @ 3.47GHz with 12 cores each
32GB of Memory
5x 1TB HDDs, split in two mirrors and one hot-spare
C: is one mirror, D: is another mirror
2x NICs: Intel NIC and Intel NIC#2
Intel NIC: "Vantage Ethernet Connection" - static 192.168.0.3/24, G 192.168.0.254, DNS 192.168.0.2
Intel NIC#2: "Local Area Connection 2 - Virtual Network" - 192.168.0.55/24 no gateway, DNS 192.168.0.2
OS and roles are installed on C:
Roles installed:
File Services
Hyper-V
Hyper V guests:
Guest #1:
Windows Small Business Server 2011
Domain controller, Exchange, File Server
Dynamic Memory (minimum 8GB maximum 24GB)
Physicall files on C:
Uses Local Area Connection 2 - Virtual Network, IP address 192.168.0.2 / 24
Guest #2:
Windows Server 2003
Line of Business application running Database
Static memory (4GB)
Physical files on D:
Uses Vantage Ethernet Connection, IP Address 192.168.0.10 / 24
Here are the issues they are describing:
1. When you perform any operation on Outlook there is approximately a 40 second delay. When they click to send the Email they will have to wait 10 to 40 seconds for the window to close
2. The line of business application my client uses is very slow to go from section to section, which connects to the Server 2003
3. Opening cad files from the network and saving them is very very slow
SBSSRV cpu is running at a good 5%, and memory at 87%
HYPER-V HOST is running at a good 5% and Physical Memory 48%
I have attached a sreenshot of the Performon results for both HYPER-V HOST and SBSSRV
Also attached a resource monitor screenshot also for both HYPER-V HOST and SBSSRV
I think the issue is either Disk or Network, but im unsure of what to do next to fix the issue.
Thanks.

It's a shame because you've got a top spec machine, 32GB, Dual Xeons, 12 Core each.
It's unlikely to be network, it takes alot to saturate a 1Gb network.
What's the Storage system SATA, 7,200rpm?

The thing is that I have a very similar configuration in another client of many, with a HyperV host and 2x Guests, one running SBS 2011 and one running Terminal Server (25+ concurrent users). Their hardware is much smaller than the one described above, and they don't experience this bottleneck, eventhough they also run 2x Mirrorrs
SATA 7,200rpm disks?
Does your other client run a database?
ASKER
Hitachi HUA72201 SATAII 7200 3.0 gbps
ASKER
no, no database on the other one
Yes, it's possible the database, which is cuasing the issue on SATA drives. Sorry, but that's the bottleneck, good server, let down by poor storage.

I think I just found what the issue was. We have an Endpoint Security Antivirus from our Monitoring Agent (n-able), that uses the panda enginem installed on both SBS & Database server. I have just uninstalled it completely and the HDD usage dropped by nearly half. I find it strange it didn't come up on the resource monitor, but maybe I just wasn't looking long enough.
I will be performing some more tests and will get client to test the performance as well. Will keep you updated.
We have about 5 snapshots in one of the servers as well and im thinking of removing them to see if it helps too.... but I have to have a good read about it, I'm not sure if its as easy as just deleting them, of if deleting may revert the server back to the initial state.
Will keep you posted.
Thanks for the help mate.

Hey mate, forgot about replying to this.
The problem really was the AV as I said... thanks for the assistance and pointing the right directions

2 x RAID 1 Mirrors is not going to give top performance.
You would be better with 4 x DISKs in RAID 10, with a hot spare.
More spindles, more disks = more performance.
But SATA 7,200rpm disks are troublesome, because they cannot give the IOPS needed, upgrade to SAS, or purchase more SATA disks.
