+Performance issue running quest image on qemu compiled for Win32 platform
+
+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.
