Hello -- I am trying to optimize 2D video graphics performance for a 32
bit Winxp guest running on Ubuntu 9.04. I have done some preliminary
benchmarking and have found that vga "std" outperforms "cirrus" on most
tests by about 20%-40%. However the std option is still (depending on
the test) about 3 to 20 times slower than native 2D performance I get
using low-end on-board Intel graphics. I haven't run the benchmark in
VMWare workstation yet, but I can tell by looking that KVM is much
slower -- which has surprised me because it has performed very well in
my cpu and disk i/o tests.
I have attempted to try the "vmware" option by installing the vmware
SVGA II driver in the Winxp guest, but all I ever get with this option
is a blank screen. In reading an earlier thread in this mailing list,
somebody said that the "-vga vmware" option was only for Linux/Unix
based guests. Can anyone confirm this?
My machine has 2 quad-core 2.7Ghz AMD opterons, 16 GB RAM, and an nVidia
285 GLX card. Here is the command line I am using:
kvm -hda kvm2dperf.qcow2 -m 2G -smp 2 -k en-us -name "KVM 2D Perf" -vga
std -net nic -net user -soundhw all -cpu qemu64
Is there any other command line options or approaches for amping up
graphics performance? I am open to any/all ideas!
Thanks,
Dave
