<br>
I built spice-gtk on my low end devices and want to test their<br>
performance using SPICE.<br>
However the performance seems not so good.<br>
<br>
About the host, it's using E7500 CPU with 6G memories.<br>
CentOS 6.3 with qemu-kvm-0.12.1.2.<br>
<br>
The guest is Windows 7 with QXL drivers(No agent yet, only QXL driver)<br>
Two cores are assigned to the guest.<br>
<br>
The Cortex A8(AllWinner A10 SoC) comes with 1G RAM, Mali 400 GPU with<br>
xf86-sunxifb driver(which is funcional). The distribution is Archlinux<br>
ARM.<br>
But the spice performance is barely acceptable, when a windows<br>
animation occurs, there will a noticeable lag, and a lot of frame<br>
drops when playing a 640x480 video.<br>
<br>
The Raspberry Pi is worse since the lower spec.<br>
<br>
When comes to Atom with PVR driver, the performance does not improve too much.<br>
<br>
In fact, I hope SPICE can beat RDP when connect to a Windows guest,<br>
but overall RDP get a better graphic performance on all the three<br>
devices using xfreerdp.<br>
<br>
Would anyone share some info about how to improve the SPICE graphic<br>
performance or what I did wrong to impact the SPICE performance?<br><br></blockquote><div style>You can try:</div><div style>1) Use spicec as your spice client, since spicec use X11 as render backend, it may be more fast than spice-gtk which uses cairo as backend.</div>
<div style>2) Build spice-gtk --with-x11 --with-coroutine=ucontext(if your glibc support it)</div><div style><br></div><div style>I built spice-gtk --with-x11 on my raspberry PI but it did not improve too much(I guess this is due to the lack of accelrated X driver on RSP)</div>
