Hi Bruce,
pveperf is quite bad. From my limited experience, a tipical 7200 rpms
SATA drive gives 60 fsync/s and >100 MB/sec buffered reads. Average seek
time is very bad too (~13ms in 7200 rpm drive). If you had VMs running,
please stop them all and rerun the command.
You shouldn't used this for virtualization unless this problem is fixed
(you're already feeling the pain eh??)
What hard disk controller do you have? ('lspci')

Eneko,
Thanks for the feedback. It seems that the whole Windows system is
slow. It happens with loading applications too and loading start menu
for example so if I am understanding this right, viritio drives which
are installed after Windows is installed may not help me a lot?!
Please correct me if I am wrong. Also how can I build a virtio drive
to test it?

Hi Bruce,
pveperf on the disk (/) ?
If you haven't, I think it will help you a lot installing virtio
drivers on the Windows guest, then changing VM disks from ide to
virtio.

Thanks for feedback Krzysztof and Alexandre. Below are the info:
I am using 1x 500GB WD HDD. I can add another one if that helps -
something like: WD5001AALS. Would that help? Where do you read
the IOPS? and what is a good number of IOPS today?
For VM I am using LOCAL QCOW2 - not sure how virtio drives work.
Hoping following info help you tell me if I am hitting a
controller bottleneck (meaning I can't help it) or if it is an
HDD problem:

Hi Bruce,
Could you confirm that you are using one 500GB SATA drive as
your storage ?
How many VMs are running on this drive ?
This SATA drive is capable of 60 IOPS maybe 70IOPS, you can
easily saturate this installing windows apps, particularly if
you run simultaneous VMs on that drive
To solve your 'performace' problems you have to build RAID
and add more spindles.

Hi Everyone,
I am seeing very slow install of applications within a
Windows 2008R2 VM that I built with 24Gbs of RAM (no
users on it yet) and the Proxmox server is a DL160 G6
with Dual L5520 Xeon quad core CPUs. I don't see why this
is acting so slow. I am looking for suggestions on how to
make this work faster.
Below are my findings of IO stats and HDD specifications.
I would like to know if there is any hope to this server.
I am running Windows 2008 R2 in IDE0 and QCOW mode.
