Hi,
my bachelor thesis is about comparing ESX to KVM. Now I completed a couple of benchmarks with phoronix, but I do not really understand why there is a huge performance issue on video encoding.
please see attached graph. It shows that the physical machine has about 50 fps, while the virtualized systems on ESX and KVM have only about 13-15.
What is the reason for that huge gap? Is the video card used for encoding on the physical machine - and on the vms just the cpu?
any official source for information could help me a lot.
thanks in advance
Nico
