Also i still don't understand why is AIDA 64 showing me that the speed of the CPU is 366 MHz per core, is that right or normal?. Switching windows timer source doesn't show an influence either. **ad 2. ** booting the machine with a single vCPU has no influence. zen2 commented Oct 27, 2015 Finally it's a qemu bug: https://bugs.launchpad.net/qemu/+bug/1494350 mro95 commented Oct 27, 2015 Ah thanks for reporting @zen2 !

I've been running a stability test with the AIDA soft, and it reached only 800MHz of speed, that is a little disappointing. #6 Martin Ezequiel, Jul 7, 2015 Last edited: Only then I ran "echo vhost_net > /etc/modules". This had little effect, but is should provide more consistent performance under higher load.
