[Qemu-devel] slow HD performance in mingw
Hello all, I noticed that QEMU(both 1.2.1 and git head) acts very slow when accessing HD. I wonder if it is a fault in my build environment? Spec: Windows XP SP3 gcc-4.6.2 binutils-2.22.51.20120114 SDL-1.2.14 glib-2.28.8 (configure line: CFLAGS="-Os -I/mingw/include" LDFLAGS=-s ./configure --prefix=/mingw --disable-shared --enable-static --enable-threads --with-threads=win32 --with-libiconv=native --disable-gtk-doc-html --disable-fam --disable-xattr --disable-selinux --disable-debug ) configure line: ./configure --target-list="i386-softmmu" --audio-drv-list=sdl --audio-card-list="ac97,es1370,sb16,cs4231a,adlib,gus,hda" --disable-linux-aio --disable-vnc-jpeg --with-coroutine=windows --extra-cflags="-pipe" Regards, Roy
