Hello!
Please help me, have Installed proxmox on a hp dl 140g3 two 500 hdd raid 0 zfs software
(also RAID-proxmox but didn't see it, only two separate disk)
when testing speed
sync; dd if=/dev/zd0 of=tempfile bs=1M count=6024; sync
Produces here such indicators
6024+0 records in
6024+0 records out
6316621824 bytes (6.3 GB) copied, 12.2597 s, 515 MB/s
the test was conducted five times
During the test shows it atop
DSK |          sda  | busy     54% |  read       2 |  write   1449 | KiB/w     10  | MBr/s   0.02 |  MBw/s   1.55 |  avio 3.70 ms |
DSK | sdb | busy 50% | read 3 | write 1349 | KiB/w 12 | MBr/s 0.02 | MBw/s 1.62 | avio 3.71 ms |
iostat -x 1 shows the following at the time of testing

Create a virtual machine the raw disk controller either sata or ide did not see the difference cache Wright back memory 4000гиг
disk 50гиг

The installation takes a very long time besides at the moment eats all of the RAM.
the indicators will not lead because it makes no sense, the overall picture is the server smokes.
Tell me what's wrong? why not use the resources?
the same garbage and at the time of backup (backup stop system) server is at rest, only when you start the OS it is already visible that something began to stir but not much.

Installed Win7 and I installed the drivers for Windows offer Proxmox, through the Manager and install as the old device. After that I was able to run instead of the IDE controller VIRTIO, System work! and a little bit of increased speed. but still very small when you open the Windows, install programs, etc. the load on the hard disk is not increased. But virtual memory has become eat less. Instantly more not going away.
When testing hard drive performance is CrystalDiskMark program 5 in a virtual machine, the indicators in the screenshot.

When cleaning the cache on the host /sbin/sysctl -w vm.drop_caches=3
the disks are accelerated by almost 100%
