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?
