Title:
  Performance issue running quest image on qemu compiled for Win32
  platform

Status in QEMU:
  Expired

Bug description:
  I'm seeing performance issues when booting a guest image on qemu 1.4.0 
compiled for the Win32 platform.
  The same image boots a lot faster on the same computer running qemu/linux on 
Fedora via VmWare, and even running the Win32 exectuable via Wine performs 
better than running qemu natively on Win32.

  Although I'm not the author of the image, it is located here:
  http://people.freebsd.org/~wpaul/qemu/vxworks.img

  All testing has been done on QEMU 1.4.0.

  I'm also attaching a couple of gprof logs. For these I have disabled
  ssp in qemu by removing "-fstack-protector-all" and
  "-D_FORTIFY_SOURCE=2" from the qemu configure script.
