To measure performance decrease on VM you can do the following:

 1) measure performance of Matcher on physical server

 2) measure performance of Matcher on VM which is hosted at the same physical machine from step 1), with access to all host's CPUs and memory and with correct CPU pinning settings (with respect to NUMA and CPU allocation and local RAM memory).

Both results should be similar, with approx. 5-10% decrease on VM (depending also on virtualization technology and its configuration).

Another performance decrease is usually caused by a shared resources between VMs, at the same host machine.
