Poor QEMU Guest Performance

<< < (2/2)

ClassicHasClass:
Do other CPU choices or changing the number of cores make any difference?

I run a homebrew QEMU and compile directly from source with -O3 -mcpu=power9. It's not super-fast running x86_64 code either, mind you. TCG is heaps better than interpreted code but even so it's still relatively simplistic.

deepblue:
The only other option I have used where I have seen a difference is qemu64, and that only tells RouterOS that it has moved from a VM to an emulated OS. I do have a huge list of Intel CPU types, but I have not seen any differences when using them.
