Ok, I installed libjpeg-turbo and did the test again - force it to use
jpeg wan compression although I am in 100Mbps LAN, the result is the
same. I remembered that qemu-spice.kvm.v11 has low CPU usage (around 50%
when playing movie).

By the way, a minor issue I found, qemu-options.hx:
728 @item jpeg-wan-compression=[auto|never|allways]
729 @item zlib-glz-wan-compression=[auto|never|allways]
730 Configure wan image compression (lossy for slow links).
731 Default is auto.
but, in the ui/spice-core.c,
197 static const char *wan_compression_names[] = {
198 [ SPICE_WAN_COMPRESSION_AUTO ] = "auto",
199 [ SPICE_WAN_COMPRESSION_NEVER ] = "never",
200 [ SPICE_WAN_COMPRESSION_ALWAYS ] = "always",
201 };
So there is a typo: "allways" vs "always".
