Absurd benchmark results in Guestsystems

Reported by: Barzille Owned by:
Priority: major Component: other
Version: VirtualBox 1.5.0 Keywords: benchmark 1.5.0 nbench bonnie
Cc: Guest type: other
Host type: other

Description

Host: Ubuntu 7.04 server Guest1: Ubuntu 6.06 lts server Guest2: Ubuntu 6.06 lts server

Running tests like bonnie++ and nbench-2.2.2 return absurd results: Guest systems acquire 10times better results than its host. The tests are run seperately, not parallel on host and guest!

Bonnie++ is a io/hdd benchmark and nbench is a Bytemark CPU benchmark.

Virtualbox Version 1.5.0

The same tests on XEN and VMware server return "correct" results, so that it does not seem to be an error at those benchmark programs

I posted the results as JPG, I hope it'll help you. Today I re-benchmarked with Virtualboxvdersion 1.5.1 but guestsystem still acquires higher values than hostsystem.

Do you have guest additions installed or not? Please check if vboxadd-timesync is running in the guest.

I did not have installed it then.

But now I have and still get the same result!
