On win XP host, recompiling with gcc-3.3.3 instead of gcc-3.2.3 gave
some improvements. But the top is a certain patch posted some weeks
ago. See below...

(Host is winXPpro, guest is bbc-2.1.iso cdrom)
(all my recompilations are with msys/mingw+gcc-3.3.3)

qemu-0.6.0 (binaries from qemu's website)           = ~17 MB/s
qemu-0.6.0 (recompiled with msys/mingw+gcc-3.3.3)   = ~17.5 MB/s
qemu-0.6.1 (cvs *with* suggested pci-ide DMA PATCH) = ~47 MB/s !!!! :))

Please look back at this mailing list archives to get the
"suggested pci-ide DMA PATCH".
