Wine performances compared to qemu

Post by pcouderc » Tue Sep 10, 2019 2:00 am

I use wineconsole to compile some FTN stuff in a .bat file.
Compared to the same .bat files executed under kvm-qemu, wine is about 10 times longer.

My question is :
- Is normal ?
- If yes, why ?
- If no, what am I missing ?

Thanks

(Sorry for the delay in answering, I use wine for years but as it works so fine, I did not need help, so my posts are delayed for approval....!)

Still don't know what you mean, though.

Sure...
There are many cases. But the simpler to explain is :
I have installed and I run MSVC++6 under wine. It works fine, I can compile and build a C++ project.
But why is it much more slow than building the same project in MSVC++5 under kvm-qemu ?
Is it normal ?
Is it by design ? wine cannot be quicker than qemu.
Or it is by my mistake ? I have some bad parameter not set...
Thank you.

You mean Wine is slower than windows in a VM?

That would warrant a bugreport. Do you have a test program?

Mmm, it is not easy... I should find a way to simplify the example.
But I understand that, from your opinion, this is not normal. It may be a bug, but I doubt it for the moment, it is surer to suppose that I have done some mistake as I do not know id some parameter should be added... About memory, for example...?
