[Qemu-devel] some benchmarks on windows hosts

[Christian MICHON]

Just wanted to share some preliminary results

Aim= to compare on WinXP hosts qemu+kqemu 0.7.1
         with Serenity Virtual Station (svista)

Settings= both vm use 128M RAM + 256M HDD/COW
Guest= slaxpro iso 

Benchmarks= boot time, untarring kernel, compile kernel
Time is measured in real time, not in vm time. :)

Results:
======
boot time -> 34s (qemu)     42s (svista)
untarring -> 102s (qemu)    83s (svista)
compile  -> 230s (qemu)    247s (svista)

3 remarks out of this experiment:

1) qemu cdrom emulation is faster than svista
   (I've other testbenches showing it: bartpe for ex)

2) qemu hdd could be faster (kqemu doesn't improve this)
  (it seems the old hdd udma patches never made it inside CVS)

3) speed of calculation is faster now with qemu+kqemu
 ( I read somewhere that on Windows, only Svista was a real
  competitor to VmWare supremacy. Apparently now qemu is
  a good challenger too)
