Converting from Console is 2x faster than using CLI

[jaolma]

Hi!

I'v been testing Hyper-V to ESXi VM/disk migration. What I noticed is that when I use the CLI (V2V_ConverterConsole.exe), network transfer speed is about 0.5Gbps. When I do the exact same migration job with Console (V2V_Converter.exe), network transfer speed is around 1Gbps. I tried everyway around and get the same results. Why is this? Can anyone else duplicate this issue?

Unrelated, but when I tried the VMware Converter, it also gave me only 0.5Gbps, until I disabled the SSL encryption. The I got around 1Gbps.

Also a feature request: It would be great, when converting a multi disk VM, the disks conversions would go parallel rather than serial.

Great product btw.

Jani,

Thanks for your request! I will forward it to the dev team.

Any news about the speed issue?

Unfortunately, I have no update.

Interesting!
I usually get around 3.2 to 3.5 Gbps speed, no matter which SW I use (cli or gui). But I am going the other way (VMware to HV).

I feel my speeds are too slow, because on both sides we have very fast, all flash Pure storage arrays. I think SW is single threaded and that is causing the speed limitation.
