Hi,
ReplyDeletedid you perform those tests on a fully virtualized or on a para-virtualized KVM domU/guest?
Greetings and many thanks for your benchmarks,
Michael
Thanks! I was wondering which is fastest since I can't seem to get KVM to perform as fast as VirtualBox does even though all tests show KVM wins to VirtualBox.
