vSphere 5.0 system, gigabit NICs everywhere.
I'm trying to use ovftool (3.5.0, Win64-bit ver. running on Win 2008R2) to export and import a large set of VMs. When I use the ovftool to export from vSphere to OVA files, transfer speed sits around 1MB/sec. I can't for the life of me figure out why?
Using the vSphere 5.0 Client GUI (File > Export...) it goes quickly (~20MB/sec). If I export the exact same VM to the exact same storage location using ovftool it's slow. If I then import that VM back to vSphere using ovftool, it goes quickly... it's only the export from vSphere to OVA using ovftool that's slow.
Thoughts?
I'm still experiencing this with 4.0.0 as well. Below is the section of code I'm trying to run using powercli:
Invoke-Expression '& "C:\Program Files\VMware\VMware OVF Tool\ovftool.exe" --noSSLVerify -tt=ova "vi://user@vCenter/datacenter/vm/folder/vmname" "$path"'
Again, it's working but REALLY slow, see below. Both are from the same vSphere Client, and both are saving to the same network location.
Hi,
maybe antivirus...
I tried disabling McAfee on-access scan and the Windows Firewall and that made no difference. I also inspected Resource Monitor and found nothing exciting happening there (top CPU user was OVFtool at 10%, and negligible disk activity since this is being stored directly to network storage). I feel like I'm either missing something in the ovftool arguments, or there's a significant difference between the recent OVFTools and the vSphere 5.0 Client OVF engines.
