qemu win10 host winxp quest very slow

[Dario Ciriminna]

Hello folks,

i need to compile and run qemu under Windows 10 host (Pentium G860, very 
bad)  with a Windows XP guest.
Precompiled downloaded binary run smoothly, but my compiled version is 
very very slow (I NEED to compile it).

I start it with :

"C:\Program Files\qemu\qemu-system-x86_64w.exe" .\WindowsXP.img -m 1024M 
-usb -vga std -netdev user,id=n0 -device rtl8139,netdev=n0 -fda 
.\ZSK_DSK.img -D .\qemu.log

ah and -D .\qemu.log doesn't log nothing. 0k log file.

What can i try ? 3 min to start Windows XP is unacceptable and after 
start system run slow!

Thanks for help

Dario
