[Spice-devel] spice 0.6.3 slower than 0.4?

Hi Alon

I think your guess is correct, the mjpeg codec.
Mjpeg will make local CPU/GPU work harder since you have a long list of jpeg
need to reassemble on the client end.

Just curious why do you pick mjpeg over ffmpeg ?

Last year test:
We tested 0.4 with slow laptop (1.2Ghz ULV CPU ). It ran fine with flash.
I could still do thing the the old laptop while VDI/flsash was running.

Forward today:
I have a Netbook, not much better in term of raw CPU, but
I can't do anything if I have VDI/sflash running. CPU is 80-100% !
Same CPU issues with my old 1.2Ghz ULV CPU laptop.

This happen in both Linux (we build it) .
and Windows spice clients (we downloaded).

Our test setup:
Guest VDI is Ubuntu 10.10  ( could not get WindowsXP/7/32-64 bit to 
install QXL drivers that we download from spice-space)
Host KVM is RHEL 6

Thanks
