WHY QEMU is the most slowest running program?

[MacPlussed]

I was installing Mac OS 9.1. But why QEMU works very slowly and spends time. I am using 512 MB of RAM as memory. But QEMU is still running very slowly. I am using QEMU's latest Windows 64-bit program.
Here is my new Code:

Code: Select all

qemu-system-ppc.exe -L pc-bios -M mac99 -m 512 -prom-env "boot-args=-v" -prom-env "vga-ndrv?=true" -boot d -drive file=macos_91_ppc.iso,format=raw,media=cdrom -drive file=MacOSX.img,format=raw,media=disk -device usb-mouse -device usb-kbd -netdev user,id=network01 -device sungem,netdev=network01

Is the host computer using a Celeron CPU? Is it an older processor?

The Windows build is known to be slower than the Linux and Mac builds; it also doesn't perform very well on older CPUs with less cache.

I use Intel i5, I think this error comes from the QEMU version. Because I ran Mac OS 9 into the old QEMU and QEMU never slowed down.

Are you sure you run this command line?

qemu-system-ppc.exe -L pc-bios -M mac99 -m 512 -prom-env "boot-args=-v" -prom-env "vga-ndrv?=true" -boot d -drive file=macos_91_ppc.iso,format=raw,media=cdrom -drive file=MacOSX.img,format=raw,media=disk -device usb-mouse -device usb-kbd -netdev user,id=network01 -device sungem,netdev=network01

That will not run from the hard disk image.

You need:

qemu-system-ppc.exe -L pc-bios -M mac99 -m 512 -prom-env "boot-args=-v" -prom-env "vga-ndrv?=true" -boot c -drive file=MacOSX.img,format=raw,media=disk -drive file=macos_91_ppc.iso,format=raw,media=cdrom -device usb-mouse -device usb-kbd -netdev user,id=network01 -device sungem,netdev=network01

to boot from HD.

Which older version is faster for you? I haven't noticed any Windows build being particularly slow compared to others.
Windows builds are roughly 10% slower compared to Linux/OSX builds.

The QEMU version 20171215 on this site is very fast.

But I will install Mac OS 9.1 on HD, why do I do it?
