No bandwidth limit, on client I saw use between 1 and 3 mb, both server
and client have 1 gbps cabled network (lan).
Server used for testing is a dell PE T310 with cpu xeon X3450 is asus
K53S with core i5-2430M.
Server cpu usage of qemu process is over 300% on streming video.
spice streaming video setting is 'all' and codec 'gstreamer:vp8', no
error/warning in qemu logs.
I used github.com/fgouget/spice-gtk/commits/gst including "avoid
gstreamer deadlock" and github.com/fgouget/spice/commits/gst in latest test.
Client cpu and network usage seems low but streaming video is bad (with
vp8), here a small video example done with smartphone:

I'm going crazy, I'm not understand what can be the problem :(
Is more probable client or server side problem? What I must check better?

Thanks for any reply and sorry for my bad english.
