If you run ReactOS native, is it slow?
I compile ReactOS trunk and 0.3 daily, but (when both work) they are really slow when running executables. Mouse movement becomes delayed, and it's if the CPU is on full load; but it can't be, unless there's a bug. However, it's not so slow running in Qemu. What's the problem? What config.rbuild options should I have? I have a pentium-m CPU, so that's the option I've set. Should it be different?

As long as it is in such a early state, it will hopefully stay this way. It is tested and bugtracked on a VM, because of nice features, like COM to Log-File etc and it allows you tons of other things you hardly can do with a 2nd PC. Why trying to run it on all possible PCs and risking its stability in the main Bugfixing Environment, a VM? It's alpha and is not meant to be used as a main OS. If you really want to try it, then use a VM.
You should use qemu with kqemu accelerator
I don't run reactos natively anymre since several weeks, because the installation once crunched the primary partition table of the 2nd HDD. Other disadvantage: in alpha stage it's a bit difficult to include vendor drivers for real hardware (graphics + network card) into real installation.
Reactos comes with some native XGA/SVGA and NE2000 drivers for virtual hardware emulated by qemu.
qemu + kqemu give good or very good performance results for reactos, even on an older P4 (1500Mhz).
You would think it is running native on a P1 or P2.
But I found performance with Qemu alone, WITHOUT accelerator rather disappointing.
Not yet tested XEN (needs an extra trunk?)
or vmware (pay-ware).
In the early days (ros <= 0.2.3) i once tested reactos with Bochs (=terribly poor performance).

Re: You should use qemu with kqemu accelerator
That doesn't surprise me. That's because qemu without the accelerator module emulates the guest CPU instead of running the code natively as it does with the accelerator module. The point is that you can use qemu on, say, a PowerPC or SPARC machine, which doesn't wor with VMware or similar.steveh wrote:But I found performance with Qemu alone, WITHOUT accelerator rather disappointing.
