I installed Proxmox on a HP Proliant N40L server. It has a 1.5Ghz 2-core processor and 8GB of Ram. It also has an HP Smart Array P410 controller with dual 2TB Samsung hard drives configured in a RAID1. I've allocated 7GB to a Windows 2008 R2 virtual machine. I attached a 3TB Seagate Expansion external hard drive and used USB Redirector to passthrough (the only way I have been able to get USB to the client). When transferring any large files, it consistently only gives me around 8-9Mb/sec. I have set the hard drive as virtio and added:
to the VMID.conf. I've verified that Virtualization and AHCI are both turned on in the BIOS. I've also turned the hard drive write cache on in both the bios and the P410 controller. In Proxmox, I've set the VM hard drive to cache=none. When I run pveperf I get:
When I copy a file between two different partitions in Windows Server 2008, it starts out at around 70-80Mb/sec and then steadily falls to around 50mb/sec. When I move the external Seagate drive to my laptop and attach directly, it gives me around 20-30MB/sec.
Is all of this normal or is there a way to increase this speed?
