Recently I had an unpleasant surprise while trying to convert a physical machine to a virtual one.
The estimated conversion time shown by VMware Converter was… a modest… 4.5 hours, all because of encryption.
I understand encryption when transmitting over a public network, but over a LAN…?!
After disabling encryption, the transfer took 40 minutes.
